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…
Cosmic Birefringence and Electroweak Axion Dark Energy
Gongjun Choi, Weikang Lin, Luca Visinelli +1
Taking the recently reported non-zero rotation angle of the cosmic microwave background (CMB) linear polarization as the hint for a pseudo Nambu-Goldston…
Gravitino Cosmology Helped by a Right Handed (S)Neutrino
Gongjun Choi, Tsutomu T. Yanagida
In this paper, we discuss interesting scenarios resulting from the interplay between the gravitino and the lightest right-handed (s)neutrino. We consider two gravitino mass regimes…
Charms of Strongly Interacting Conformal Gauge Mediation
Gongjun Choi, Tsutomu T. Yanagida, Norimi Yokozaki
By extending a previously proposed conformal gauge mediation model, we construct a gauge-mediated SUSY breaking (GMSB) model where a SUSY-breaking scale, a messenger mass, the -…
