Production of two Higgses at the Large Hadron Collider in CP-violating MSSM

Understand

Production of two Higgs bosons is studied in a CP violating supersymmetric scenario at the Large Hadron Collider with $E_{cm}=14$ TeV.

• There exists a region where a very light Higgs $\lesssim 50$ GeV could not be probed by LEP experiment.
• This leads to so called 'LEP hole' region.
• Recently LHC found a Higgs boson around $\sim 125$ GeV, which severely constrains the possibility of having lighter Higgs bosons, which cannot be detected, i.e., buried Higgs, in this model.
