Abstract We present the NLO electroweak radiative corrections to production in γγ collision, which is an ideal channel for calibrating beam luminosity of a Photon Linear Collider. analyze dependence total cross section on colliding energy, and then investigate kinematic distributions final particles at various initial photon polarizations EW accuracy. The numerical re...

We use holographic techniques to study photon production in a class of finite temperature, strongly coupled, large-Nc SU(Nc) quark-gluon plasmas with Nf ≪ Nc quark flavours. Our results are valid to leading order in the electromagnetic coupling constant but non-perturbatively in the SU(Nc) interactions. The spectral function of electromagnetic currents and other related observables exhibit an i...

In this paper, it is shown that in hadron-nucleus and nucleus-nucleus collisions, the main source for central exclusive diffractive Higgs production is photon-photon fusion. At the LHC energy, the total cross section for this process is about 0.6 pb (for proton-gold scattering), and 3.9 nb (for gold-gold collision) while the gluon-gluon fusion leads to the value of the cross section for CED Hig...

Radiating a photon from the initial state provides a useful tool for studying a range of low energy physics using a high-energy ee accelerator. Accurate results require careful calculation of the first order virtual photon corrections. We compare exact results for initial state radiative corrections, finding agreement to an order of 10 or better as a fraction of the Born cross-section for most ...

A photon collider luminosity and its energy are determined by the parameters of an electron-electron linear collider (energy, power, beam emittances) and collision effects. The main collision effect is the coherent e+e− pair creation. At low energies (2E< 0.5–1 TeV) this process is suppressed due to repulsion of electron beams. In this region Lγγ(z > 0.65) ≥ 1035cm−2s−1 is possible (1033 − 1034...

In the last several years the nucleon’s spin structure functions have been extensively studied by deep inelastic scattering of polarized leptons on polarized nucleon targets. Recently there has been growing interest in the polarized photon structure function. Especially its first moment has attracted much attention in the literature in connection with the axial anomaly. Now the information on t...

Laser Compton scattering (LCS) light sources can provide high-energy photons from keV to MeV range. Many research and development projects of linac-based LCS sources are carried on. For the photon energies of tens keV, linac-based LCS sources realize laboratory-size X-ray sources, of which performance is potentially comparable to 2 generation synchrotron light sources. Linac-based LCS also real...
