Diffractive Higgs production from Dual String Theory
Resumen
We will apply the methods of string theory to make predictions of hadrons interactions at the new hadronic collider LHC. We shall study the Higgs particle production in proton anti-proton scattering in the diffractive process where the hadrons remain unchanged and just scatter through a small angle without internal excitation or disruption. A Higgs particle is produced with central rapidity, in the Regge limit where two pomerons are exchanged (double Regge limit). The impossibility to make predictions about this phenomenon just using perturbative quantum chromo-dynamics (QCD) is supplanted by the powerful methods of the gauge-gravity correspondence (also known as Maldacena conjecture). Using such a paradigm, the calculation of that amplitude will be performed in supergravity, modelizing the Higgs particle as a non-normalizable dilaton mode. The reason for that is because in the one-loop Standard Model the Higgs field couples to gluons through a dimension five operator. We expect to meet the technical challenge of fusing two pomerons in such a non-normalizable mode. The study of this reaction is not present in the literature and we believe it can be important for the master students, involved in this project, in order to apply their knowledge for solving a very high level academicals problem as well as for making predictions about the current experiments in particle physics.
