  1. intrinsic Higgs Production from Heavy Quarks Iván Schmidt Universidad Federico Santa María (Chile) SILAFAE 2009

  2. Outline • Higgs production. • Intrinsic heavy quarks. • Large production. • Different production processes. • Results. • Conclusions.

  3. Unknown mass • Small production probability and large backgrounds • Coupling ~ mass hard to observe in pp Higgs detection Production at central rapidities

  4. But : Small (1% probability for c) ~ Heavy quarks in proton large p H (compensated by fermion-Higgs coupling) Production at large Reduce backgrounds from multiparticle production

  5. 1) Non-perturbative (stationary state) 300 MeV 2) Perturbative (quantum fluctuation) Large production Experimentally: • DIS data, excess at large Double-charm baryons • SELEX data

  6. Possible processes Inclusive Higgs production Semi-inclusive Higgs production Exclusive diffractive production

  7. Inclusive production

  8. Final result • For LHC energy (14 TeV cm) • Perturbative heavy flavors • Includes absorptive corrections ( 20% at LHC) • IT falls for GeV • Heavy quark probability ~ p p p H p • Large rapidity gap • Missing mass measurement

  9. Heavy quark components carry high momentum fractions. • Higgs production in fragmentation region. • Diffractive production • Also possible: , . • Difficult detection . Conclusions S. Brodsky B. Kopeliovich I. S. Nucl. Phys. B807 (2009) 334

  10. Hope to see some of you in Chile in two years Gracias
