Relic density of wino-like dark matter in the MSSM
M. Beneke, A. Bharucha, F. Dighera +4
The relic density of TeV-scale wino-like neutralino dark matter in the MSSM is subject to potentially large corrections as a result of the Sommerfeld effect. A recently developed f…
Heavy neutralino relic abundance with Sommerfeld enhancements - a study of pMSSM scenarios
M. Beneke, C. Hellmann, P. Ruiz-Femenia
We present a detailed discussion of Sommerfeld enhancements in neutralino dark matter relic abundance calculations for several popular benchmark scenarios in the general MSSM. Our…
Non-relativistic pair annihilation of nearly mass degenerate neutralinos and charginos III. Computation of the Sommerfeld enhancements
M. Beneke, C. Hellmann, P. Ruiz-Femenia
This paper concludes the presentation of the non-relativistic effective field theory formalism designed to calculate the radiative corrections that enhance the pair-annihilation cr…
Non-relativistic pair annihilation of nearly mass degenerate neutralinos and charginos II. P-wave and next-to-next-to-leading order S-wave coefficients
C. Hellmann, P. Ruiz-Femenia
This paper is a continuation of an earlier work (arXiv:1210.7928) which computed analytically the tree-level annihilation rates of a collection of non-relativistic neutralino and c…
Non-relativistic pair annihilation of nearly mass degenerate neutralinos and charginos I. General framework and S-wave annihilation
M. Beneke, C. Hellmann, P. Ruiz-Femenia
We compute analytically the tree-level annihilation rates of a collection of non-relativistic neutralino and chargino two-particle states in the general MSSM, including the previou…
