In this talk, we study some of the consequence of one example of a beyond the Standard Model theory. Namely, we discuss a model based on a spontaneously broken $B-L$ gauge symmetry. It can explain the light neutrino masses via a Type-I seesaw mechanism with heavy neutrinos. From the limits on the light neutrinos masses due to double beta decay experiments and cosmological observations together...
Cascade of particles injected due to the decay and annihilation of dark matter (DM) particles and Primordial black hole (PBH), which has gained increasing interests as an alternative candidate for DM, can potentially change the cosmic recombination history by ionizing and heating the intergalactic medium, which results in altering the anisotropy spectra of the Cosmic Microwave Background...
Abstract: A light CP-even scalar $S$ with mass below GeV-scale exists in may beyond standard model (SM) scenarios. Such a light particle can be produced abundantly in the stars, such as the Sun, red giants, white dwarfs, horizontal-branch stars, neutron star mergers, and supernovae. In this talk I will show the state-of-art stellar limits on $S$. Assuming the couplings of $S$ to the SM...
We investigate simplified models involving an inert scalar triplet and vector-like leptons that can account for the muon g−2 anomaly. These simplified scenarios are embedded in a model that features W' and Z' bosons, which are subject to stringent collider bounds. The constraints coming from the muon g−2 anomaly are put into perspective with collider bounds, as well as bounds coming from...
