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…

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…
