This paper describes the idea of the particle recognition at the Pattern Comparator Boards at the RPC detector at the CMS experiment at the LHC at CERN. This solution enables the muons and the Heavy Stable Charged Particles recognition and distinguishing. The described algorithms are implemented in the FPGA structures. They are able to realise the fast analysis of the data from the whole system and work on the reliable triggering decision with the same delay. The implementation is compared with the other solutions. The further development of the RPC system for the HSCPs search is described. Those solutions should provide the reliable data about the hipotetical existence of the HSCPs.

The question as to how this universe came into being and as to how it has evolved to its present stage, is an old question. The answer to this question unfolds many secrets regarding fundamental particles and forces between them. Theodor Kaluza proposed the concept that the universe is composed of more than four space-time dimensions. In his work electromagnetism is united with gravity. Various extra dimensions formulations have been proposed to solve a variety of problems. Recently, the idea of more than four space time dimensions is applied to the search for particle identity of dark matter (DM).Signature of dark matter can be revealed by analysis of very high energy electrons which are coming from outer space. We investigate dynamical conditions of annihilation channels of Lightest Kaluza Klien particle LKP which is suggested to be concrete evidence of dark matter in galactic subhalos [1-9].

Due to fundamental limitations of accelerators, only cosmic rays can give access to centre-of- mass energies more than one order of magnitude above those reached at the LHC. In fact, extreme energy cosmic rays (1018 eV - 1020 eV) are the only possibility to explore the 100 TeV energy scale in the years to come. This leap by one order of magnitude gives a unique way to open new horizons: new families of particles, new physics scales, in-depth investigations of the Lorentz symmetries. However, the flux of cosmic rays decreases rapidly, being less than one particle per square kilometer per year above 1019 eV: one needs to sample large surfaces. A way to develop large-effective area, low cost, detectors, is to build a solar panel-based device which can be used in parallel for power generation and Cherenkov light detection. Using solar panels for Cherenkov light detection would combine power generation and a non-standard detection device.

The LHC is an opportunity to make a change. By thinking, and speaking publicly, about fundamental concepts that underlie physical theory, the physicist may both accrue public interest in his work and contribute to the analysis of the foundations of modern physics.

The LHC FP420 R&D project is assessing the feasibil- ity of installing forward proton detectors at 420m from the ATLAS and/or CMS interaction points. Such detec- tors aim at measuring diffracted protons, which have lost less than 2% of their longitudinal momentum. The success of this measurement requires a very good understanding of the charged and neutral particle environment in the de- tector region in order to avoid the signal being swamped as well as for detector survivability. This background re- ceives contributions from beam-gas interactions, halo par- ticles surviving from the betatron and momentum cleaning systems and secondaryshowers producedby particles from the 14 TeV collision region striking the beampipe upstream of the FP420 detectors. In this paper, such background sources are reviewed, and the expected background rates calculated.

The UA9 experimental equipment was installed in the CERN-SPS in March '09 with the aim of investigating crystal assisted collimation in coasting mode. Its basic layout comprises silicon bent crystals acting as primary collimators mounted inside two vacuum vessels. A movable 60 cm long block of tungsten located downstream at about 90 degrees phase advance intercepts the deflected beam. Scintillators, Gas Electron Multiplier chambers and other beam loss monitors measure nuclear loss rates induced by the interaction of the beam halo in the crystal. Roman pots are installed in the path of the deflected particles and are equipped with a Medipix detector to reconstruct the transverse distribution of the impinging beam. Finally UA9 takes advantage of an LHC-collimator prototype installed close to the Roman pot to help in setting the beam conditions and to analyze the efficiency to deflect the beam. This paper describes in details the hardware installed to study the crystal collimation during 2010.
