Inert-Sterile Neutrino: Cold or Warm Dark Matter Candidate
Graciela B. Gelmini, Efunwande Osoba, Sergio Palomares-Ruiz
In usual particle models, sterile neutrinos can account for the dark matter of the Universe only if they have masses in the keV range and are warm dark matter. Stringent cosmologic…
The Schwinger-Dyson equation on Pomeron loop summation and renormalization
J. Miller
The solution to the Schwinger-Dyson equation that describes the summation over Pomeron loop diagrams is derived. The solution is a closed expression which splits into two parts. Th…
Dark matter detection in the BMSSM
Nicolas Bernal, Andreas Goudelis
The addition of non-renormalizable terms involving the Higgs fields to the MSSM (BMSSM) ameliorates the little hierarchy problem of the MSSM. For neutralino dark matter, new region…
Minimal Flavour Violation and Multi-Higgs Models
F. J. Botella, G. C. Branco, M. N. Rebelo
We propose an extension of the hypothesis of Minimal Flavour Violation (MFV) to general multi-Higgs Models without the assumption of Natural Flavour Conservation in the Higgs secto…
General method of solution of Schwinger-Dyson equations in Minkowski space
V. Sauli, Z. Batiz
Novel solutions of Minkowski QED2+1 and large QCD Schwinger-Dyson equations will be presented and discussed. The resultant propagators of confined degrees of freedom will be…
Trimaximal lepton mixing with a trivial Dirac phase
W. Grimus, L. Lavoura, A. Singraber
We present a model which employs the seesaw mechanism with five right-handed neutrinos, leading to trimaximal and CP-conserving lepton mixing. Tri-bimaximal mixing is a natural lim…
