Neutrinos from Off-Shell Final States and the Indirect Detection of Dark Matter
, 2012 We revisit the annihilation of dark matter to neutrinos in the Sun near the WW and tt kinematic thresholds. We investigate the potential importance of annihilation to WW* in a minimal dark matter model in which a Majorana singlet is mixed with a vector ...

He jishu, 2023 BackgroundThe annihilation radiation exhibits conspicuous features in the low-energy segment of the orbital gamma spectrum, which contains a substantial amount of geological information about the lunar surface.

CMB data constraint on self-annihilation of dark matter particles
, 2010 Recently, self-annihilation of dark matter particles is proposed to explain the "WMAP Haze" and excess of energetic positrons and electrons in ATIC and PAMELA results.

Conservative upper limits on WIMP annihilation cross section from Fermi-LAT $\gamma$-rays [PDF]
, 2011 The spectrum of an isotropic extragalactic $\gamma$-ray background (EGB) has been measured by the Fermi-LAT telescope at high latitudes. Two new models for the EGB are derived from the subtraction of unresolved point sources and extragalactic diffuse ...

Annihilation of charged particles [PDF]
Physical Review E, 1996 The kinetics of irreversible annihilation of charged particles performing overdamped motion induced by long-range interaction force, $F(r)\sim r^{- }$, is investigated. The system exhibits rich kinetic behaviors depending on the force exponent $ $. In one dimension we find that the densities decay as $t^{-1/(2+ )}$ and $t^{-1/(1+2 )}$ when $ >1$

Annihilation of Highly-Charged Topological Defects
Crystals, 2020 We studied numerically external stimuli enforced annihilation of a pair of daughter nematic topological defect (TD) assemblies bearing a relatively strong topological charge |m|=3/2.

Journal of High Energy Physics, 2012 Neutralino dark matter in supersymmetric models is revisited in the presence of flavor violation in the soft supersymmetry breaking sector. We focus on flavor violation in the sleptonic sector and study the implications for the co-annihilation regions.

Neutralino annihilation into gluons [PDF]
Physical Review D, 1994 We present a complete calculation of the cross section for neutralino annihilation into the two-gluon final state. This channel can be quite important for the phenomenology of neutralino annihilation due to the well-known helicity suppression of neutralino annihilation into light quarks and leptons.

P-Wave Positron-Hydrogen Scattering, Annihilation, and Positronium Formation
Atoms, 2017 In a previous paper (Bhatia A.K. 2016), a hybrid theory for the scattering of positrons from hydrogen atoms was applied to calculate S-wave phase shifts, annihilation, and positronium formation cross sections.
