Consequences of neutrino self interactions for weak decoupling and big bang nucleosynthesis
E. Grohs, George M. Fuller, Manibrata Sen
We calculate and discuss the implications of neutrino self-interactions for the physics of weak decoupling and big bang nucleosynthesis (BBN) in the early universe. In such neutrin…
Fast Neutrino Flavor Instability in the Neutron-star Convection Layer of Three-dimensional Supernova Models
Robert Glas, H. -Thomas Janka, Francesco Capozzi +4
Neutrinos from a supernova (SN) might undergo fast flavor conversions near the collapsed stellar core. We perform a detailed study of this intriguing possibility, analyzing time-de…
On the Impact of Neutrino Decays on the Supernova Neutronization-Burst Flux
André de Gouvêa, Ivan Martinez-Soler, Manibrata Sen
The discovery of non-zero neutrino masses invites one to consider decays of heavier neutrinos into lighter ones. We investigate the impact of two-body decays of neutrinos on the ne…
Flavoured leptogenesis and symmetry
Rome Samanta, Manibrata Sen
We present a systematic study of leptogenesis in neutrino mass models with -flavoured CP symmetry. In addition to the strong hierarchical -dominated scenario (DS) in…
Accessible Lepton-Number-Violating Models and Negligible Neutrino Masses
André de Gouvêa, Wei-Chih Huang, Johannes König +1
Lepton-number violation (LNV), in general, implies nonzero Majorana masses for the Standard Model neutrinos. Since neutrino masses are very small, for generic candidate models of t…
Supernova neutrinos: fast flavor conversions near the core
Manibrata Sen
Neutrino flux streaming from a supernova can undergo rapid flavor conversions almost immediately above the core. Focusing on this region, we study these fast conversions using a li…
