Heavy quarks at Tevatron/LHC

• Gregory Moreau (Laboratoire de Physique Theorique d'Orsay (LPTh))

Room: Amphi Dirac Exotic quarks appear in several extensions of the Standard Model. Those have been searched in recent Tevatron data and will also be testable using first year LHC resuts. I will discuss in particular how one could distinguish between a heavy quark being a fourth generation against a custodian arising in warped extra-dimensional models.

Searching for lepton jets at hadron colliders

• Adam Falkowski (Laboratoire de Physique Theorique d'Orsay (LPTh))

Room: Salle du Conseil A lepton jet is a cluster of highly collimated charged particles: electrons, and possibly muons and pions. Lepton jets can be produced in colliders in a class of theories that contains light (GeV scale, or less) hidden sector particles. I will review the strategies to search for these objects at hadron colliders. I will talk in more detail about one method, proposed in 1007.3496, to discriminate high multiplicity electron jets from QCD jets. The main discriminating variables are the jet electromagnetic fraction and charge ratio. The efficiency for rejection of QCD jets is estimated to be of order 10^−3 per jet.

Boosted massive jets @ LHC

• Lee Seung (Weizmann Institute, Tel Haviv)

Room: Salle du Conseil I will talk about the emergence of boosted massive jets (such as top or Higgs jets) at the LHC, and the nature of the problem (finite resolution). Then, I will talk about recent development of semi-analytical tools, including jet mass distribution and jet-substructure to understand signal and QCD background. In particular, I will present a new class of infrared safe jet observables, template overlaps, designed to filter targeted highly boosted particle decays from QCD jets and other background. Possible hints for New Physics from Tevatron will be also discussed. Talk based on:arXiv:1006.2035, arXiv:0810.0934, arXiv:0807.0234, and work in progress.
