Basis independent neutrino masses in the violating MSSM
Sacha Davidson, Marta Losada
We calculate the neutrino mass matrix up to one loop order in the MSSM without R-parity, including the bilinears in the mass insertion approximation. This introduces additional dia…
Constraints on both bilinear and trilinear R-parity violating couplings from neutrino laboratories and astrophysics data
Asmaa Abada, Marta Losada
We consider neutrino masses generated at tree level and at one loop, through fermion--sfermion loop diagrams, in the MSSM with R-parity violation. Using the mass and…
Neutrino masses in the R-parity violating MSSM
Sacha Davidson, Marta Losada
We compute one loop neutrino masses in the R-parity violating Minimal Supersymmetric Model, including the bilinear R-parity violating masses in the mass insertion approximation. To…
Two-loop dimensional reduction and effective potential without temperature expansions
M. Laine, M. Losada
In many extensions of the Standard Model, finite temperature computations are complicated by a hierarchy of zero temperature mass scales, in addition to the usual thermal mass scal…
Baryogenesis at Low Reheating Temperatures
Sacha Davidson, Marta Losada, Antonio Riotto
We note that the maximum temperature during reheating can be much greater than the reheating temperature at which the Universe becomes radiation dominated. We show that the S…
