Pion condensation in the early Universe at nonvanishing lepton flavor asymmetry and its gravitational wave signatures
Volodymyr Vovchenko, Bastian B. Brandt, Francesca Cuteri +3
We investigate the possible formation of a Bose-Einstein condensed phase of pions in the early Universe at nonvanishing values of lepton flavor asymmetries. A hadron resonance gas…
Shedding New Light on Sterile Neutrinos from XENON1T Experiment
Soroush Shakeri, Fazlollah Hajkarim, She-Sheng Xue
The XENON1T collaboration recently reported the excess of events from recoil electrons, possibly giving an insight into new area beyond the Standard Model (SM) of particle physics.…
Primordial Gravitational Wave Signals in Modified Cosmologies
Nicolás Bernal, Anish Ghoshal, Fazlollah Hajkarim +1
Modified expansion rates in the early Universe prior to big bang nucleosynthesis are common in modified gravity theories, and can have a significant impact on the generation of dar…
