The PAMELA excess from neutralino annihilation in the NMSSM
Yang Bai, Marcela Carena, Joseph Lykken
We examine whether the cosmic ray positron excess observed by PAMELA can be explained by neutralino annihilation in the Next-to-Minimal Supersymmetric Standard Model (NMSSM). The m…
The Baryogenesis Window in the MSSM
Marcela Carena, Germano Nardini, Mariano Quiros +1
Electroweak baryogenesis provides an attractive explanation of the origin of the matter-antimatter asymmetry that relies on physics at the weak scale and thus it is testable at pre…
Light Stop Searches at the LHC in Events with One Hard Photon or Jet and Missing Energy
M. Carena, A. Freitas, C. E. M. Wagner
Low energy supersymmetric models provide a solution to the hierarchy problem and also have the necessary ingredients to solve two of the most outstanding issues in cosmology: the o…
The Effective Theory of the Light Stop Scenario
Marcela Carena, Germano Nardini, Mariano Quiros +1
Electroweak baryogenesis in the minimal supersymmetric extension of the Standard Model may be realized within the light stop scenario, where the right-handed stop mass remains clos…
Heavy Quarks Above the Top at the Tevatron
Anupama Atre, Marcela Carena, Tao Han +1
Recent developments in models with warped extra dimensions have opened new possibilities for vector-like quark studies at hadron colliders. These new vector-like quarks can mix siz…
Higgs Signal for h to aa at Hadron Colliders
Marcela Carena, Tao Han, Gui-Yu Huang +1
We assess the prospect of observing a neutral Higgs boson at hadron colliders in its decay to two spin-zero states, a, for a Higgs mass of 90-130 GeV, when produced in association…
