Parity-violation in bouncing cosmology

چکیده
We investigate the possibility of enhancement parity-violation signal in bouncing cosmology. Specifically, we are interested deciding which phase should generate most significant signals. find that dominant contribution comes from phase, while contraction has a smaller contribution. Therefore, cosmology can enhance signals during phase. Moreover, since highest energy scale cosmology, also probe new physics at this by studying effect.

Bouncing Cosmology in Three Dimensions
We consider a dynamical two-brane in a four dimensional black hole background with scalar hair. At high temperature this black hole goes through a phase transition by radiating away the scalar. The end phase is a topological adS-Schwarzschild black hole. We argue here that for a sufficiently low temperature, the brane motion in this geometry is non-singular. This results in a universe which pas...
متن کاملParity violation in atoms
Optical experiments have demonstrated cases in which mirror symmetry in stable atoms is broken during the absorption or emission of light. Such results, which are in conflict with quantum electrodynamics, support the theory of unification of the electromagnetic and weak interactions. The interpretation of the experimental results is based on exchanges of weak neutral Z0 bosons between the elect...
متن کاملParity Violation in Astrophysics
Core collapse supernovae are gigantic explosions of massive stars that radiate 99% of their energy in neutrinos. This provides a unique opportunity for large scale parity or charge conjugation violation. Parity violation in a strong magnetic field could lead to an asymmetry in the neutrino radiation and recoil of the newly formed neutron star. Charge conjugation violation in the neutrino-nucleo...
متن کاملBouncing cosmology from Kalb-Ramond Braneworld
We consider a 3-brane embedded in a warped 5-dimensional background with a dilaton and a Kalb-Ramond 2-form. We show that it is possible to find static solutions of the form of charged dS/AdS-like black hole with horizon which could have a negative mass parameter. The motion of the 3-brane in this bulk generates an effective 4dimensional bouncing cosmology induced by the negative dark radiation...
