Warm dark matter sterile neutrinos in electron capture and beta decay spectra
O. Moreno, E. Moya de Guerra, M. Ramón Medrano
We briefly review the motivation to search for sterile neutrinos in the keV mass scale, as dark matter candidates, and the prospects to find them in beta decay or electron capture…
Role of Sterile Neutrino Warm Dark Matter in Rhenium and Tritium Beta Decays
H. J. de Vega, O. Moreno, E. Moya de Guerra +2
Sterile neutrinos with mass in the range of one to a few keV are important as extensions of the Standard Model of particle physics and are serious dark matter (DM) candidates. This…
Semiclassical and Quantum Black Holes and their Evaporation, de Sitter and Anti-de Sitter Regimes, Gravitational and String Phase Transitions
Marina Ramon Medrano, Norma G. Sanchez
An effective string theory in physically relevant cosmological and black hole space times is reviewed. Explicit computations of the quantum string entropy, partition function and q…
Semiclassical (QFT) and Quantum (String) anti - de Sitter Regimes: New Results
A. Bouchareb, M. Ramon Medrano, N. G. Sanchez
We compute the quantum string entropy S_s(m, H) from the microscopic string density of states of mass m in Anti de Sitter space-time. For high m, (high Hm -->c/α'), no phase transi…
The SL(2,R)WZWN string model as a deformed oscillator and its classical-quantum string regimes
M. Ramon Medrano, N. G. Sanchez
We study the SL(2,R) WZWN string model describing bosonic string theory in AdS_3 space-time as a deformed oscillator together with its mass spectrum and the string modified SL(2,R)…
Semiclassical (Quantum Field Theory) and Quantum (String) de Sitter Regimes: New Results
A. Bouchareb, M. Ramon Medrano, N. G. Sanchez
We compute the quantum string entropy S_s(m, H) from the microscopic string density of states rho_s (m,H) of mass m in de Sitter space-time. We find for high m, a {\bf new} phase t…
