“…The high energy muon beam at CERN allows to measure Hard Exclusive Meson Production or Deeply Virtual Compton Scattering (DVCS) in the Bjorken regime in a large range of Q^2 and x_Bj (1.5<Q^2<7.5 GeV^2 and 0.03<x_Bj<0.25). …”

“…Especially from directions close to the Galactic Plane, the expected gamma-ray spectrum is altered via two effects: directly, by the photons emitted in the bremsstrahlung process on the interstellar gas by energetic electrons which are among the DM annihilation byproducts; indirectly, by the modification of the same electron spectrum, due to the additional energy loss process in the diffusion-loss equation (e.g. the resulting inverse Compton emission is altered). We quantify the importance of the bremsstrahlung emission in the GeV energy range, showing that it is the dominant component of the gamma-ray spectrum for some cases. …”

“…The basic physics processes for charged particles, photons, neutrons and neutrinos are mostly electromagnetic (collision losses described by Bethe-Bloch, bremsstrahlung, photo-electric effect, Compton scattering and pair production) for charged particles and photons; additional strong interactions for hadrons; neutrinos interacting weakly with matter. …”

“…In this publication we discuss possible explanations, in particular the statistical fluctuations of the deposited charge and the Compton electron flight time distributions. Moreover, we rediscuss the reduction of the Townsend coefficient due to the space charge effect inside the avalanches as a function of the avalanche size. …”

“…The most direct measurement of gluon densities and kinematics in hadronic collisions is the inverse Compton process (𝑞+𝑔→𝛾+𝑞). The LHCb experiment measured pairs of isolated photons correlated with hadrons from the quark fragmentation in pPb and Pbp collisions at 8.16 TeV probing a Bjorken-𝑥 between 10^{-5}…”

“…With the COMPASS experiment at CERN, pion-photon reactions are investigated via the Primakoff effect, implying that high-energetic pions react with the quasi-real photon field surrounding the target nuclei.The production of a single hard photon in such a pionscattering at lowest momentum transfer to the nucleus is related to pionCompton scattering. From the measured cross-section shape, the pion polarisability is determined. …”
