Neutrino Phenomenology, Dark Energy and Leptogenesis from pseudo-Nambu-Goldstone Bosons
C. T. Hill, I. Mocioiu, E. A. Paschos +1
We consider a model of dynamical neutrino masses via the see-saw mechanism. Nambu-Goldstone bosons (majorons) arise associated with the formation of the heavy right-handed majorana…
Low-Energy Thermal Leptogenesis in an Extended NMSSM Model
Ernest Ma, Narendra Sahu, Utpal Sarkar
Thermal leptogenesis in the canonical seesaw model in supersymmetry suffers from the incompatibility of a generic lower bound on the mass scale of the lightest right-handed neutrin…
Constraints on flavor-dependent long range forces from solar neutrinos and KamLAND
Abhijit Bandyopadhyay, Amol Dighe, Anjan S. Joshipura
Flavor-dependent long range (LR) leptonic forces, like those mediated by the or gauge bosons, constitute a minimal extension of the standard model that preserv…
CP violation in neutrino mass matrix
Utpal Sarkar, Santosh K. Singh
We constructed rephasing invariant measures of CP violation with elements of the neutrino mass matrix, in the basis in which the charged lepton mass matrix is diagonal. We discuss…
Thermal leptogenesis in extended supersymmetric seesaw
M. Hirsch, M. Malinsky, J. C. Romao +2
We consider an extended supersymmetric SO(10) seesaw model with only doublet Higgs scalars, in which neutrino masses are suppressed by the scale of D-parity violation. Leptogenesis…
Working Group Report: Heavy-Ion Physics and Quark-Gluon Plasma
Munshi G. Mustafa, Sudhir Raniwala, T. Awes +20
This is the report of Heavy Ion Physics and Quark-Gluon Plasma at WHEPP-09 which was part of Working Group-4. Discussion and work on some aspects of Quark-Gluon Plasma believed to…
