Search for the neutral Higgs bosons of the minimal supersymmetric standard model in pp collisions at √s=7 TeV with the ATLAS detector [PDF]

open access: yes, 2013
A search for neutral Higgs bosons of the Minimal Supersymmetric Standard Model (MSSM) is reported. The analysis is based on a sample of proton-proton collisions at a centre-of-mass energy of 7 TeV recorded with the ATLAS detector at the Large Hadron ...
