Testing high scale supersymmetry via second order gravitational waves
Marcos M. Flores, Alexander Kusenko, Lauren Pearce +2
Supersymmetry predicts multiple flat directions, some of which carry a net baryon or lepton number. Condensates in such directions form during inflation and later fragment into Q-b…
Quantum Gravity Effects on Dark Matter and Gravitational Waves
Stephen F. King, Rishav Roshan, Xin Wang +2
We explore how quantum gravity effects, manifested through the breaking of discrete symmetry responsible for both Dark Matter and Domain Walls, can have observational effects throu…
Did we hear the sound of the Universe boiling? Analysis using the full fluid velocity profiles and NANOGrav 15-year data
Tathagata Ghosh, Anish Ghoshal, Huai-Ke Guo +5
In this paper, we analyse sound waves arising from a cosmic phase transition where the full velocity profile is taken into account as an explanation for the gravitational wave spec…
Decay of the Mediator Particle at Threshold
Shigeki Matsumoto, Yu Watanabe, Yuki Watanabe +1
A light mediator particle is often predicted in the dark sector scenario, which weakly interacts with the standard model (SM) particles. The weakness of the interaction is usually…
The Effective Potential in Fermi Gauges Beyond the Standard Model
Jonathan Zuk, Csaba Balazs, Andreas Papaefstathiou +1
We derive the field-dependent masses in Fermi gauges for arbitrary scalar extensions of the Standard Model. These masses can be used to construct the effective potential for variou…
Bremsstrahlung High-frequency Gravitational Wave Signatures of High-scale Non-thermal Leptogenesis
Anish Ghoshal, Rome Samanta, Graham White
Inflaton seeds non-thermal leptogenesis by pair producing right-handed neutrinos in the seesaw model. We show that the inevitable graviton bremsstrahlung associated with inflaton d…
