The post-inflationary cosmology of the VISH axion-majoron model
Alexei H. Sopov, Carlos Tamarit, Raymond R. Volkas
It was previously shown how several explanatory deficiencies of the Standard Model (including the origin of dark matter, matter-antimatter asymmetry, small active neutrino mass, st…
Challenges and Opportunities of Gravitational Wave Searches above 10 kHz
Nancy Aggarwal, Odylio D. Aguiar, Diego Blas +34
The first direct measurement of gravitational waves by the LIGO and Virgo collaborations has opened up new avenues to explore our Universe. This white paper outlines the challenges…
The QCD theta-parameter in canonical quantization
Wen-Yuan Ai, Bjorn Garbrecht, Carlos Tamarit
The role of the QCD theta-parameter is investigated in pure Yang-Mills theory in the spacetime given by the four-dimensional Euclidean torus. While in this setting the introduction…
Dark matter freeze-in from non-equilibrium QFT: towards a consistent treatment of thermal effects
Mathias Becker, Emanuele Copello, Julia Harz +1
We study thermal corrections to a model of real scalar dark matter (DM) interacting feebly with a SM fermion and a gauge-charged vector-like fermion mediator. We employ the Closed-…
Instability of bubble expansion at zero temperature
Wen-Yuan Ai, Juan S. Cruz, Bjorn Garbrecht +1
In the context of false vacuum decay at zero temperature, it is well known that bubbles expand with uniform proper acceleration. We show that this uniformly accelerating expansion…
The limits of the strong problem
Wen-Yuan Ai, Juan S. Cruz, Bjorn Garbrecht +1
While violation has never been observed in the strong interactions, the QCD Lagrangian admits a -odd topological interaction proportional to the so called angle, which…
