Can the Higgs be seen in rapidity gap events at the Tevatron or the LHC ?
Double diffractive Higgs production at pp (or p̄p) colliders continues to attract attention as a potential signal in the search for the boson. We present improved perturbative QCD estimates of the event rates for both the exclusive and inclusive double diffractive Higgs processes, paying particular attention to the survival probability of the rapidity gaps. We find that the major uncertainty is ...
متن کاملThe rapidity gap Higgs signal at LHC
We compare the WW and pomeron-pomeron fusion mechanisms for the doublediffractive production of a Higgs boson. We determine the suppression of the ‘rapidity gap’ pomeron-pomeron fusion events due to QCD radiative effects. In particular we use leading log techniques to estimate the cross sections for both exclusive and inclusive double-diffractive Higgs production at LHC energies. The same appro...
متن کاملRapidity Gap Events in Squark Pair Production at the LHC
The exchange of electroweak gauginos in the t− or u−channel allows squark pair production at hadron colliders without color exchange between the squarks. This can give rise to events where little or no energy is deposited in the detector between the squark decay products. We discuss the potential for detection of such rapidity gap events at the Large Hadron Collider (LHC). Our numerical analysi...

متن کاملCan an invisible Higgs boson be seen via diffraction at the LHC ?
We study the possibility of observing an ‘invisible’ Higgs boson in central exclusive diffractive production at the LHC. We evaluate the cross section using, as a simple example, the Standard Model with a heavy fourth generation, where the invisible decay mode H → ν4ν̄4 dominates, with the heavy neutrino mass M(ν4) ≃ 50 GeV. We discuss the possible requirements on trigger conditions and the back...
