Leptogenesis with a GeV-Scale Quasi-Dirac Neutrino
Stephen F. King, Soumen Kumar Manna, Rishav Roshan +1
We discuss leptogenesis in a model with a GeV-scale quasi-Dirac neutral lepton, comprising mainly sterile states, which is accessible to future experiments. In particular, we show…
Reconciling ALP Dark Matter and Electroweak Baryogenesis through First-Order Electroweak Phase Transition
Dipendu Bhandari, Soumen Kumar Manna, Arunansu Sil
We show that an axionlike particle (ALP) can simultaneously generate the baryon asymmetry and constitute dark matter through dynamics triggered by a first-order electroweak phase t…
Impact of First-order Electroweak Phase Transition on QCD Axion
Dipendu Bhandari, Soumen Kumar Manna, Arunansu Sil
The QCD axion addresses the strong CP problem and dark matter via the misalignment mechanism, typically requiring a decay constant GeV), unless the in…
Probing ALP-portal fermionic dark matter at the colliders
Subhaditya Bhattacharya, Sahabub Jahedi, Soumen Kumar Manna +1
Axion-like particles (ALPs) are promising candidates for mediating interactions between a dark sector and the Standard Model (SM). In this work, considering the effective interacti…
Leptogenesis with Majoron Dark Matter
Stephen F. King, Soumen Kumar Manna, Rishav Roshan +1
We discuss a model of neutrino mass based on the type I seesaw mechanism embedded in a spontaneously broken global lepton number framework with a symmetry. We show that the r…
Spontaneous Leptogenesis with sub-GeV Axion Like Particles
Arghyajit Datta, Soumen Kumar Manna, Arunansu Sil
A derivative coupling of an axion like particle (ALP) with a B-L current may lead to the baryon asymmetry of the universe via spontaneous leptogenesis provided a lepton number brea…
Effects of Electroweak Symmetry Breaking on Axion Like Particles as Dark Matter
Soumen Kumar Manna, Arunansu Sil
Axion like particles (ALPs), the pseudo Nambu-Goldstone bosons associated to the spontaneous breaking of global symmetry, have emerged as promising dark matter candidates. Conventi…
Majorons Revisited: light dark matter as FIMP
Soumen Kumar Manna, Arunansu Sil
We show that Majoron, the pseudo-Nambu-Goldstone boson resulting from the spontaneous breaking of global lepton number symmetry, can present itself as a viable freeze-in type of da…
