Gamma-ray signal from Dark Matter Annihilation mediated by mixing scalar mediators
Fei Teng
We present here a study of the direct and indirect detection prospects of a generic dark matter simplified model, in which the Majorana dark matter interacts only with a Standard M…
Correspondence between Solutions of Scattering Equations and Scattering Amplitudes in Four Dimensions
Yi-Jian Du, Fei Teng, Yong-Shi Wu
In this talk, we review our recent work on direct evaluation of tree-level MHV amplitudes by Cachazo-He-Yuan (CHY) formula. We also investigate the correspondence between solutions…
Direct Evaluation of -point single-trace MHV amplitudes in 4d Einstein-Yang-Mills theory using the CHY Formalism
Yi-Jian Du, Fei Teng, Yong-Shi Wu
In this paper we extend our techniques, developed in a previous paper (Du, etc, JHEP 05(2016)086) for direct evaluation of arbitrary -point tree-level MHV amplitudes in 4d Yang-…
Characterizing the solutions to scattering equations that support tree-level gauge/gravity amplitudes
Yi-Jian Du, Fei Teng, Yong-Shi Wu
In this paper we define, independent of theories, two discriminant matrices involving a solution to the scattering equations in four dimensions, the ranks of which are used to divi…
Simplified Dark Matter Models with Charged Mediators: Prospects for Direct Detection
Pearl Sandick, Kuver Sinha, Fei Teng
We consider direct detection prospects for a class of simplified models of fermionic dark matter (DM) coupled to left and right-handed Standard Model fermions via two charged scala…
Gamma-ray Signals from Dark Matter Annihilation Via Charged Mediators
Jason Kumar, Pearl Sandick, Fei Teng +1
We consider a simplified model in which Majorana fermion dark matter annihilates to charged fermions through exchange of charged mediators. We consider the gamma-ray signals arisin…
CHY formula and MHV amplitudes
Yi-jian Du, Fei Teng, Yong-Shi Wu
In this paper, we study the relation between the Cachazo-He-Yuan (CHY) formula and the maximal-helicity-violating (MHV) amplitudes of Yang-Mills and gravity in four dimensions. We…
