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…
Instanton-mediated baryon number violation in non-universal gauge extended models
J. Fuentes-Martin, J. Portoles, P. Ruiz-Femenia
Instanton solutions of non-abelian Yang-Mills theories generate an effective action that may induce lepton and baryon number violations, namely , being the num…
Non-resonant effects in the top-antitop resonance region
Pedro Ruiz-Femenia
The recent developments on the computation of non-resonant corrections to the e+ e- -> W+ W- b bbar cross section in the top-antitop resonance region are reviewed in this talk. Non…
Electroweak non-resonant NLO corrections to e+ e- -> W+ W- b bbar in the t tbar resonance region
M. Beneke, B. Jantzen, P. Ruiz-Femenia
We analyse subleading electroweak effects in the top anti-top resonance production region in e+ e- collisions which arise due to the decay of the top and anti-top quarks into the W…
