The DFSZ axion in the CMB
Ricardo Z. Ferreira, Alessio Notari, Fabrizio Rompineve
We perform for the first time a dedicated analysis of cosmological constraints on DFSZ QCD axion models. Such constructions are especially interesting in light of the recent Xenon-…
Decay of Boson Stars with Application to Glueballs and Other Real Scalars
Mark P. Hertzberg, Fabrizio Rompineve, Jessie Yang
One of the most interesting candidates for dark matter are massive real scalar particles. A well-motivated example is from a pure Yang-Mills hidden sector, which locks up into glue…
Quantitative Analysis of the Stochastic Approach to Quantum Tunneling
Mark P. Hertzberg, Fabrizio Rompineve, Neil Shah
Recently there has been increasing interest in alternate methods to compute quantum tunneling in field theory. Of particular interest is a stochastic approach which involves (i) sa…
Ultralight Scalar Decay and the Hubble Tension
Mark Gonzalez, Mark P. Hertzberg, Fabrizio Rompineve
We examine whether the Hubble tension, the mismatch between early and late measurements of , can be alleviated by ultralight scalar fields in the early universe, and we assess…
The tension: vs.
Guillermo Ballesteros, Alessio Notari, Fabrizio Rompineve
We investigate whether the tension on between SHES 2019 and Planck 2018 can be alleviated by a variation of Newton's constant between the early and the lat…
