Neutrino Splitting and Density-Dependent Dispersion Relations
Emilio Ciuffoli, Jarah Evslin, Xiaojun Bi +1
We show that particles can split only when their group velocity exceeds their phase velocity. In this sense the splitting process is the quantum analog of the modulational instabil…
Search for dark matter signals with Fermi-LAT observation of globular clusters NGC 6388 and M 15
Lei Feng, Qiang Yuan, Peng-Fei Yin +2
The globular clusters are probably good targets for dark matter (DM) searches in -rays due to the possible adiabatic contraction of DM by baryons. In this work we analyse the th…
Probing Light Stop Pairs at the LHC
Xiao-Jun Bi, Qi-Shu Yan, Peng-Fei Yin
In this work, we study the light stop pair signals at the LHC. We explore the SUSY parameter space with non-universal gaugino and third generation masses at the GUT scale. Recent L…
Constraints and tests of the OPERA superluminal neutrinos
Xiao-Jun Bi, Peng-Fei Yin, Zhao-Huan Yu +1
The superluminal neutrinos detected by OPERA indicates Lorentz invariance violation (LIV) of the neutrino sector at the order of . We study the implications of the result…
Cosmic ray spectral hardening due to dispersion of source injection spectra
Qiang Yuan, Bing Zhang, Xiao-Jun Bi
The cosmic ray (CR) energy spectra measured with ATIC, CREAM and PAMELA showed that there is remarkable hardening for rigidity of several hundred GV. We propose that this hardening…
Breit-Wigner Enhancement Considering the Dark Matter Kinetic Decoupling
Xiao-Jun Bi, Peng-Fei Yin, Qiang Yuan
In the paper we study the Breit-Wigner enhancement of dark matter (DM) annihilation considering the kinetic decoupling in the evolution of DM freeze-out at the early universe. Sinc…
