A concept of the transition radiation detector for a hadron separation in a forward direction of the LHC experiments
/ Belyaev, N (Moscow Phys. Eng. Inst.) ; Cherry, M L (Louisiana State U.) ; Doronin, S A (Moscow Phys. Eng. Inst.) ; Filippov, K (Moscow Phys. Eng. Inst.) ; Fusco, P (Bari Polytechnic ; INFN, Bari) ; Gargano, F (Bari Polytechnic) ; Konovalov, S (Lebedev Inst.) ; Loparco, F (Bari Polytechnic ; INFN, Bari) ; Mazziotta, M N (Bari Polytechnic) ; Mufazalova, A (Moscow Phys. Eng. Inst.) et al.
Studying of hadron production in forward direction at the LHC energy has a great interest both for understanding of the fundamental QCD processes and also in applied areas such as the description of ultra-high energy cosmic particle interactions. The energies of secondary hadrons in such studies almost reach the maximum energy available at the LHC of ~6 TeV, which corresponds to a Lorentz γ-factor up to 104 and above. [...]

Registration of the transition radiation with GaAs detector: Data/MC comparison
/ Alozy, J (CERN) ; Belyaev, N ; Bergmann, B L (IEAP CTU, Prague) ; Billoud, T R V (IEAP CTU, Prague) ; Broulim, P (Pilsen, Coll. Mech. Elect. Eng.) ; Burian, P (IEAP CTU, Prague ; Pilsen, Coll. Mech. Elect. Eng.) ; Campbell, M (CERN) ; Chelkov, G (Dubna, JINR) ; Cherry, M (Louisiana State U.) ; Dachs, F (CERN) et al.
New developments of pixel detectors based on GaAs sensors offer effective registration of the transition radiation (TR) X-rays and perform simultaneous measurements of their energies and emission angles. This unique feature opens new possibilities for particle identification on the basis of maximum available information about generated TR photons. [...]

Fine structure of angular distribution of x-ray transition radiation from multilayered radiator in Geant4
/ Savchenko, A A (Moscow Phys. Eng. Inst. ; Kurchatov Inst., Moscow ; Belgorod State U.) ; Tishchenko, A A (Moscow Phys. Eng. Inst. ; Kurchatov Inst., Moscow ; Belgorod State U.) ; Sergeeva, D Yu (Moscow Phys. Eng. Inst. ; Kurchatov Inst., Moscow ; Belgorod State U.) ; Belyaev, N (Moscow Phys. Eng.

The present version of the Transition Radiation (TR) simulation module implemented in the Geant4 toolkit describes very well experimental data for the TR energy distribution; however, it does not allow reproducing the details of angular distribution at small angles. In order to solve this problem, corrections to the existing x-ray TR module in Geant4 are proposed. [...]

Sensitivity of the SHiP experiment to light dark matter
/ SHiP Collaboration
Dark matter is a well-established theoretical addition to the Standard Model supported by many observations in modern astrophysics and cosmology. In this context, the existence of weakly interacting massive particles represents an appealing solution to the observed thermal relic in the Universe. [...]

Transition radiation measurements with a Si and a GaAs pixel sensor on a Timepix3 chip
/ Dachs, F (CERN ; TU Vienna) ; Alozy, J (CERN) ; Belyaev, N (Moscow Phys. Eng. Inst.) ; Bergmann, B L (CTU, Prague) ; van Beuzekom, M (Nikhef, Amsterdam) ; Billoud, T R V (Montreal U.) ; Burian, P (CTU, Prague ; Pilsen, Coll. Mech. Elect. Eng.) ; Broulim, P (Pilsen, Coll. Mech. Elect. Eng.) ; Campbell, M (CERN) ; Chelkov, G (Dubna, JINR) et al.
Growing energies of particles at modern or planned particle accelerator experiments as well as cosmic ray experiments require particle identification at gamma-factors ($\gamma$) of up to ∼ 10$^5$ . At present there are no detectors capable of identifying charged particles with reliable efficiency in this range of $\gamma$ . [...]

Studies of the spectral and angular distributions of transition radiation using a silicon pixel sensor on a Timepix3 chip

X-ray transition radiation detectors (TRDs) are used for particle identification in both high energy physics and astroparticle physics. In most of the detectors, emission of the X-ray transition radiation (TR) starts at Lorentz factors above γ∼500 and reaches saturation at γ∼2÷3⋅103 . [...]

Measurement of the energy spectra and of the angular distribution of the Transition Radiation with a silicon strip detector
/ Loparco, F (Bari Polytechnic ; Bari U. ; INFN, Bari) ; Alozy, J (CERN) ; Belyaev, N (Moscow Phys. Eng. Inst.) ; Campbell, M (CERN) ; Cherry, M (Louisiana State U.) ; Dachs, F (CERN ; Vienna, Tech.

We plan to develop an advanced Transition Radiation Detector (TRD) for hadron identification in the TeV momentum range, based on the simultaneous measurement of the energies and of the emission angles of the Transition Radiation (TR) X-rays with respect to the radiating particles. To study the feasibility of this project, we have carried out a beam test campaign at the CERN SPS facility with 20 GeV/c electrons and muons up to 300 GeV/c. [...]
