Impacts of the Higgs mass on vacuum stability, running fermion masses and two-body Higgs decays
Zhi-zhong Xing, He Zhang, Shun Zhou
The latest results of the ATLAS and CMS experiments indicate 116 GeV \lesssim M_H \lesssim 131 GeV and 115 GeV \lesssim M_H \lesssim 127 GeV, respectively, for the mass of the Higg…
Two-zero Textures of the Majorana Neutrino Mass Matrix and Current Experimental Tests
Harald Fritzsch, Zhi-zhong Xing, Shun Zhou
In view of the latest T2K and MINOS neutrino oscillation data which hint at a relatively large theta_13, we perform a systematic study of the Majorana neutrino mass matrix M_nu wit…
Comment on astrophysical consequences of a neutrinophilic 2HDM
Shun Zhou
Several authors have pointed out that the scalar-mediated interaction of neutrinos in a neutriophilic two-Higgs-doublet model (nu2HDM) can be as strong as electromagnetic interacti…
Systematic search for successful lepton mixing patterns with nonzero theta_13
Werner Rodejohann, He Zhang, Shun Zhou
We perform a systematic search for simple but viable lepton mixing patterns. Our main criterion is that the mixing matrix can be parameterized by three rotation angles, which are s…
Radiative corrections and explicit perturbations to the tetra-maximal neutrino mixing with large theta_13
He Zhang, Shun Zhou
The tetra-maximal neutrino mixing pattern predicts a relatively large reactor mixing angle theta_13 \approx 8.4^\circ, which is in good agreement with the latest best-fit value the…
Relatively large theta13 and nearly maximal theta23 from the approximate S3 symmetry of lepton mass matrices
Shun Zhou
We apply the permutation symmetry S_3 to both charged-lepton and neutrino mass matrices, and suggest a useful symmetry-breaking scheme, in which the flavor symmetry is explicitly b…
The Glashow resonance as a discriminator of UHE cosmic neutrinos originating from p-gamma and p-p collisions
Zhi-zhong Xing, Shun Zhou
We re-examine the interesting possibility of utilizing the Glashow resonance (GR) channel nu_ebar + e^- to W^- to anything to discriminate between the UHE cosmic neutrinos originat…
Supernova bound on keV-mass sterile neutrinos reexamined
Georg G. Raffelt, Shun Zhou
Active-sterile neutrino mixing is strongly constrained for m_s > 100 keV to avoid excessive energy losses from supernova cores. For smaller m_s, matter effects suppress the effecti…
