Friction pressure on relativistic bubble walls
Yann Gouttenoire, Ryusuke Jinno, Filippo Sala
During a cosmological first-order phase transition, particles of the plasma crossing the bubble walls can radiate a gauge boson. The resulting pressure cannot be computed perturbat…
Effect of density fluctuations on gravitational wave production in first-order phase transitions
Ryusuke Jinno, Thomas Konstandin, Henrique Rubira +1
We study the effect of density perturbations on the process of first-order phase transitions and gravitational wave production in the early Universe. We are mainly interested in ho…
Probing PeV scale SUSY-breaking with Satellite Galaxies and Primordial Gravitational Waves
Gongjun Choi, Ryusuke Jinno, Tsutomu T. Yanagida
We study an inevitable cosmological consequence in PeV scale SUSY-breaking scenarios. We focus on the SUSY-breaking scale corresponding to the gravitino mass $m_{3/2}=100{\rm eV}-1…
Preheating from target space curvature and unitarity violation: Analysis in field space
Yohei Ema, Ryusuke Jinno, Kazunori Nakayama +1
We study particle production and unitarity violation caused by a curved target space right after inflation. We use the inflaton field value instead of cosmic time as the time varia…
