In this letter we explore the possibility of creating the baryon asymmetry of the universe during inflation and reheating due to the decay of a field associated with the inflaton. CP violation is attained by assuming that this field is complex with a phase that varies as the inflaton evolves. We consider chaotic and natural inflation scenarios. In the former case, the complex decaying field is ...

The experimental potential of e+e− Linear Colliders to explore the properties of supersymmetric particles is reviewed. High precision measurements of masses, spin-parity, gauge quantum numbers, couplings and mixings, production and decay properties will be possible in a clean environment. These achievements will allow the underlying supersymmetry breaking scheme to be revealed, the parameters o...

We present the matrix element of γγ → 4l process with four charge particles in final state. The constructions are performed in frame of Standard Model of electroweak interaction using the helicity amplitude method. Every possible polarization state of initial and final particles are considered and analyzed.
