The SuperB progress report outlines the development of a new high luminosity e+e- collider in Italy, specifically designed to explore flavor physics within the B-meson system at a center-of-mass energy of 10 GeV. With advanced accelerator techniques derived from previous colliders and a collaborative international framework, the project aims for significant operational capabilities over a projected ten-year lifespan. The design incorporates recycling of existing components to manage costs effectively while enhancing luminosity and synchrotron radiation applications.

The elementary coupling e of the photon is the same for all species of quarks and leptons, and the same also for new particles from beyond the Standard Model. Thus, e + e − annihilation produces pairs of all species, new and exotic, at similar rates. At the LHC, the gluon couples equally to all quarks and to new colored particles. However, here, this democracy is hardly evident experimentally. Soft, non-perturbative strong interactions are the dominant mechanism for particle production and involve only the light quarks and gluons. Further, because the proton is a composite object with parton distributions that fall steeply, the production cross sections are much lower for heavy particles than for light ones. At the LHC, the cross section for producing bottom quarks is of the order of 1 mb, already much lower than the total inelastic cross section. The cross section for top quark pair production at the 14 TeV LHC is expected to be about 1 nb. Production cross sections for new particles will be 1 pb or smaller. Thus, interesting events occur at rates of 10 −7 to 10 −13 of the total event rate. This implies, first, that a trigger system is needed to exclude all events but 1 in 10 6 before any data analysis is possible. Beyond this, only events with unusual and striking properties can be recognized in the much larger sample of background QCD events. A new particle or process can be studied only if its signals can be clearly discriminated from those of QCD reactions. At the ILC, the cross sections for light quark and lepton pair production are much smaller, but also more comparable to the cross sections for interesting new physics processes. The main Standard Model processes in e + e − annihilation-annihilation to quark and lepton pairs, annihilation to W + W − , and single W and Z production-all have cross sections at the pb level at 500 GeV. New particle production processes typically have cross sections of order 10-100 fb and result in events clearly distinguishable from the basic Standard Model reactions.

Status and Future Plans of the PEP-II B-Factory
C. Steier

2002

The PEP-II e+e-collider [1,2,3,4] has been operating for two years with the BaBar detector at the energy of the Upsilon 4S resonance. The peak luminosity has reached 3.3 x10 33 /cm 2 /s with 693 bunches with a positron current of 1.5 A and an electron current of 0.8 A. PEP-II has delivered in excess of 38 fb-1 of data to BaBar. The beambeam tune shift limits are approaching 0.05-0.07 horizontally and 0.03-0.05 vertically [5]. The electron cloud instability ECI enlarges the positron beam size at high currents but is reduced by a solenoidal field on the vacuum chambers [6]. The beam currents in PEP-II are being raised to increase the number of bunches and the luminosity. Over the next few years the luminosity goal for PEP-II is 10 34 /cm 2 /s.

The Super-B project accelerator status
S. Tomassini

2010

The SuperB project is an international effort aiming at building in Italy a very high luminosity e{sup +}e{sup -} (10{sup 36} cm{sup -2} sec{sup -1}) asymmetric collider at the Y(4S) energy in the CM. The accelerator design has been extensively studied and changed during the past year. The present design, based on the new collision scheme, with large Piwinski angle and the use of 'crab waist' sextupoles already successfully tested at the DA{Phi}NE {Phi}-Factory at LNF Frascati, provides larger flexibility, better dynamic aperture and spin manipulation sections in the Low Energy Ring (LER) for longitudinal polarization of the electron beam at the Interaction Point (IP). The Interaction Region (IR) has been further optimized in terms of apertures and reduced backgrounds in the detector. The injector complex design has been also updated. A summary of the project status will be presented in this paper. The SuperB collider can reach a peak luminosity of 10{sup 36} cm{sup -2} sec{...

PROGRESS OF THE PEP-II B-FACTORY
James Turner

2003

PEP-II is an e + e -B-Factory Collider located at SLAC operating at the Upsilon 4S resonance. PEP-II has delivered, over the past five years, an integrated luminosity to the BaBar detector of over 139 fb -1 and has reached a luminosity of 6.58x10 36 /cm 2 /s. Steady progress is being made in reaching higher luminosity. The goal over the next several years is to reach a luminosity of at least 2x10 34 /cm 2 /s. The accelerator physics issues being addressed in PEP-II to reach this goal include the electron cloud instability, beam-beam effects, parasitic beam-beam effects, high RF beam loading, shorter bunches, lower betay*, interaction region operation, and coupling control. A view of the PEP-II tunnel is shown in

Recent SuperB Design Choices Improve Next-Generation e e___ B-Factory Collider
S. Nikitin

2011

The SuperB international team continues to optimize the design of an electron-positron collider, which will allow the enhanced study of the origins of flavor physics. The project combines the best features of a linear collider (high single-collision luminosity) and a storage-ring collider (high repetition rate), bringing together all accelerator physics aspects to make a very high luminosity of 10³⁶ cm⁻² sec⁻¹. This asymmetric-energy collider with a polarized electron beam will produce hundreds of millions of B-mesons at the Υ(4S) resonance. The present design is based on extremely low emittance beams colliding at a large Piwinski angle to allow very low β*{sub y} without the need for ultra short bunches. Use of crab-waist sextupoles will enhance the luminosity, suppressing dangerous resonances and allowing for a higher beam-beam parameter. The project has flexible beam parameters, improved dynamic aperture, and spin-rotators in the Low Energy Ring for longitudinal polari...

The International Linear Collider. A European Perspective
Angeles Faus Golfe

2019

The International Linear Collider (ILC) being proposed in Japan is an electron-positron linear collider with an initial energy of 250 GeV. The ILC accelerator is based on the technology of superconducting radio-frequency cavities. This technology has reached a mature stage in the European XFEL project and is now widely used. The ILC will start by measuring the Higgs properties, providing high-precision and model-independent determinations of its parameters. The ILC at 250 GeV will also search for direct new physics in exotic Higgs decays and in pair-production of weakly interacting particles. The use of polarised electron and positron beams opens new capabilities and scenarios that add to the physics reach. The ILC can be upgraded to higher energy, enabling precision studies of the top quark and measurement of the top Yukawa coupling and the Higgs self-coupling. The international -- including European -- interest for the project is very strong. Europe has participated in the ILC pro...

Performance of the PEP-II B-Factory Collider at SLAC
C. Steier

Proceedings of the 2005 Particle Accelerator Conference, 2005

PEP-II is an e + easymmetric B-Factory Collider located at SLAC operating at the Upsilon 4S resonance (3.1 GeV x 9 GeV). It has reached a luminosity of 9.21x10 33 /cm 2 /s and has delivered an integrated luminosity of 710 pb-1 in one day. PEP-II has delivered, over the past six years, an integrated luminosity to the BaBar detector of over 262 fb-1. PEP-II operates in continuous injection mode for both beams boosting the integrated luminosity. The peak positron current has reached 2.45 A in 1588 bunches. Steady progress is being made in reaching higher luminosity. The goal over the next several years is to reach a luminosity of 2.1x10 34 /cm 2 /s. The accelerator physics issues being addressed in PEP-II to reach this goal include the electron cloud instability, beam-beam effects, parasitic beam-beam effects, high RF beam loading, shorter bunches, lower β y * interaction region operation, and coupling control. Figure 1 shows the PEP-II tunnel.

SuperB: next-generation e+ e-B-factory collider
Anton Bogomyagkov, Antoine Chance

The SuperB international team continues to optimize the design of an electron-positron collider, which will allow the enhanced study of the origins of flavor physics. The project combines the best features of a linear collider (high singlecollision luminosity) and a storage-ring collider (high repetition rate), bringing together all accelerator physics aspects to make a very high luminosity of 10 36 cm −2 sec −1 . This asymmetric-energy collider with a polarized electron beam will produce hundreds of millions of B-mesons at the Υ(4S) resonance. The present design is based on extremely low emittance beams colliding at a large Piwinski angle to allow very low β y without the need for ultra short bunches. Use of crab-waist sextupoles will enhance the luminosity, suppressing dangerous resonances and allowing for a higher beam-beam parameter. The project has flexible beam parameters, improved dynamic aperture, and spin-rotators in the Low Energy Ring for longitudinal polarization of the electron beam at the Interaction Point. Optimized for best colliding-beam performance, the facility may also provide high-brightness photon beams for synchrotron radiation applications.
