Flavor specific chiral framework for explaining the ATOMKI anomaly
Aditya Batra, F. R. Joaquim, Hemant Prajapati +1
Recent anomalies in nuclear transitions observed by the ATOMKI Collaboration suggest the existence of a new boson with a mass of MeV. A theoretically consistent interpret…
Sterile neutrino Dark Matter in the minimal Dirac Seesaw
J. Adhikary, A. Batra, K. Deka +1
We study sterile neutrino dark matter in a minimal Type-I Dirac seesaw framework where the states responsible for generating Dirac neutrino masses at tree level can be viable dark…
Minimal U(1) two-Higgs-doublet models for quark and lepton flavour
J. R. Rocha, H. B. Câmara, R. G. Felipe +1
In the context of the 2HDM, and assuming that neutrinos acquire masses via the Weinberg operator, we perform a systematic analysis to determine the minimal quark and lepton flavour…
The CosmoVerse White Paper: Addressing observational tensions in cosmology with systematics and fundamental physics
Eleonora Di Valentino, Jackson Levi Said, Adam Riess +533
The standard model of cosmology has provided a good phenomenological description of a wide range of observations both at astrophysical and cosmological scales for several decades.…
