The XIth International Conference on Heavy Quarks and Leptons

11 Jun 2012, 09:00 → 15 Jun 2012, 18:00 Europe/Prague

Prague

The XIth International Conference on Heavy Quarks and Leptons continues the tradition of regular scientific meetings, first started in 1993 at the Laboratori Nazionali di Frascati in Rome, Italy, under the name "Heavy Quarks at Fixed Target". In 2002 the scope was widened to include leptons with the workshop renamed to what is known as today. This workshop is dedicated to the study of the heavy quarks, namely charm, bottom and top, with obvious extensions to interesting topics involving the strange quark. Neutrino oscillation studies and new insights in mu and tau lepton phenomenology are also included.

17:15 High precision measurement of the form factors of the semileptonic decays K+- -> pi0 l+- nu (Kl3)

Semileptonic kaon decays offer the most precise determination of the CKM matrix element |Vus|. The experimental precision is however limited by the knowledge of the form factors of this decay, since these enter both the phase space integral and the detector acceptances. The NA48/2 experiment presents new measurements of the form factors of the semileptonic decays of charged kaons, based on 4.3 million Ke3 and 3.5 million Kmu3 decays, both with negligible background. The result matches the precision of the current world average on the vector and scalar form factors and allows to significantly reduce the form factor uncertainty on |Vus|. In addition, the comparison of both channels sets tight constraints on lepton flavor violation and other possible new physics.

09:25 Charm mixing and CPV in LHCb

LHCb has collected the world's largest sample of charmed hadrons. The ~1 fb–1 sample collected in 2011 is used to search for direct and indirect CP violation in charm, and to measure D0 mixing parameters. Preliminary measurements from several decay modes are presented, with complementary time-dependent and time-integrated analyses. Together, these results significantly improve upon existing measurements.

Speaker: Vladimir Gligorov (CERN)

Slides Charm4HQL_v2.key.pdf

09:50 Measurement of φs in LHCb

The determination of the CP-violating phase φs in Bs → J/ψ φ decays is one of the key goals of the LHCb experiment. Its value is predicted to be very small in the Standard Model but can be significantly enhanced in many models of new physics. We present the world’s best measurement of φs and the first observation of a non-zero ∆Γs based upon ~1 fb−1 of data collected at LHCb during 2011. φs can also be measured using the predominantly CP-odd Bs → J/ψ π π decay mode. We present this measurement and the combination of φs from both J/ψ φ and J/ψ π π decay modes. Additionally we present first results on other Bs decay modes, potentially interesting for complementary measurements of φs, such as Bs → φ φ and Bs → J/ψ K∗0 decays.

10:15 Measurement of gamma in LHCb

The LHCb experiment is a general purpose forward spectrometer operating at the Large Hadron Collider, optimized for the study of B and D hadrons. LHCb collected ~1 fb-1 of integrated luminosity during 2011 data taking, which provides unprecedentedly large samples of B hadron decays to final states involving charmed hadrons. These decays offer many complementary measurements of CP violation, in particular measurements which are sensitive to the angle gamma (phi_3) of the CKM unitarity triangle, one of the least well measured parameters of the CKM matrix. We present here world best measurements of CPV in decays sensitive to the angle gamma, including both time dependent and time integrated types of measurements.

11:00 Direct and mixing-induced CP violation in charmless two-body B decays in LHCb

CP violation in charmless charged two-body B decays provides a way to measure the CKM angle gamma from decays involving loop diagrams. Using data collected by LHCb in 2011 we reconstruct a large sample of such decay modes of B hadrons. We present measurements of direct CP violation in B(s) → K pi decays, which are the most precise presently available, as well as of direct and mixing-induced CP violation in B0 → pi+ pi- and Bs → K+ K- decays, performed for the first time at a hadron collider and the first time ever, respectively.

In particular, large samples of K+- --> pi gamma gamma and K+- --> e nu gamma decays have been collected, allowing precision tests of the Chiral Perturbation Theory. The status and first results of these analyses are presented.

08:55 Search for charged-lepton-flavor-violation in rare muon decays

Charged-lepton-flavor-violating processes are strongly suppressed in the Standard Model, therefore their observation would be a clear indication of new Physics. The MEG experiment at the Paul Scherrer Institute searches for the lepton-flavor-violating decay mu+->e+gamma.The combined result of the data taken in 2009 and 2010 is presented. The upper limit on the branching ratio obtained (BR(mu+->e+gamma)<2.4*10^-12) improves by a factor five the previous best limit and tighten constraints on new Physics models. Future prospects are also discussed. Another lepton-flavor-violating decay of the muon is mu+->e+e-e+. The Mu3e collaboration recently proposed a new experiment for searching this decay aiming at sensitivities in the range 10^-15-10^-16.

09:45 Lepton Flavor Violation in tau and B meson decays.

Lepton flavor violating decays such as τ -> μ+ μ- μ+ or B- -> D(*)+ μ- μ- are sensitive probes of New Physics (NP). The discovery of neutrino oscillations implies that at some level there is lepton flavor violation, and in many well motivated extensions of the SM the effects are expected to be visible in τ -> μ+ μ- μ+ decays. LHCb is well suited for this analysis due to the large tau production from charm decays and LHCb’s excellent invariant mass resolution. Like-sign dimuon final states such as B- -> D(*)+ μ- μ- can be sensitive to the existence of Majorana neutrinos. The status of these analyses with ~1 fb–1 of pp collisions collected by LHCb in 2011 at √s=7 TeV is reviewed.

The LHC will produce large numbers of top anti-top quark pairs providing an excellent opportunity to study in detail the properties of the top-quark. A possibility that has not been explored experimentally so far is that of CP violating interactions of the top. We discuss the use of T-odd correlations to extract information on the CP violating couplings of the top-quark at the LHC. We illustrate our discussion with two examples: CP violating anomalous top quark couplings; and CP violation in extended Higgs sectors.

LHCb is well suited for these analyses due to its large acceptance and trigger efficiency, as well as its excellent invariant mass resolution and lepton identification capabilities.

17:20 4th generation searches at ATLAS

Among the places to look for deviations from the SM are new quarks families that can appear as a fourth family with Higgs, a “strong” fourth family without Higgs or vector-like quarks. A potential extension for the SM would be the adjonction a 4th family of heavy chiral fermions that could provide new sources of CP violation to explain the matter-antimatter asymmetry in the Universe, and allow for a heavier Higgs boson while remaining consistent with other precision electroweak studies. This poster will review various searches for 4th generation quarks performed using data collected in 7 TeV LHC proton-proton collisions with the ATLAS detector.

17:20 Physics with Tau Lepton Final States in ATLAS

Physics involving tau lepton signatures form an integral part of the ATLAS physics program, and are becoming more prevalent, given the large amounts of data accumulated in 2011 and 2012 LHC running. This talk reviews the increased sensitivity of searches for a Standard Model Higgs boson in the low mass region, as well as searches for neutral and charged supersymmetric Higgs bosons, decaying to tau final states. Other searches involving tau lepton signatures are also reviewed, including searches for heavy gauge bosons, leptoquarks, and supersymmetric decays. Standard Model processes from W, Z, and top pair production involving tau leptons are also investigated.

Speaker: Nils Ruthmann (Albert-Ludwigs-Universitaet Freiburg (DE))

17:20 Reconstruction and Identification of Hadronically Decaying Tau Leptons at ATLAS

Tau leptons will play an important role in the physics program at the LHC. They will be used not only in searches for new phenomena like the Higgs boson or Supersymmetry and electroweak measurements but also in detector related studies like the determination of the missing transverse energy scale. Optimal identification of hadronically decaying tau leptons is achieved by using detailed information from tracking and calorimeter detector components. Variables describing the properties of calorimeter energy deposits and track reconstruction within tau candidates are combined in multi-variate discriminants, to achieve high rejection against backgrounds. The identification efficiencies are measured by W->taunu and Z->tautau events, and compared with the prediction of the Monte Carlo simulation. The energy scale uncertainties for tau leptons are determined by investigating single hadron calorimeter response, as well as kinematic distributions in Z->tautau events.

Speaker: David Thomas Jennens (University of Melbourne (AU))

17:20 Top A_FB and charge asymmetry in chiral U(1)' model with flavored Higgs doublets

We construct flavor-dependent chiral U(1)' models with a Z' boson which couples to the right-handed up-type quarks in the standard model. To make the models have realistic renormalizable Yukawa couplings, we introduce new Higgs doublets with nonzero U(1)' charges. Anomaly-free condition can be satisfied by adding extra chiral fermions. We show that these models could analyze the discrepancy between the SM prediction and empirical data in the top forward-backward asymmetry at the Tevatron. We also discuss the top charge asymmetry at the LHC in this model. We emphasize that unlike the simple Z' model, our model could be compatible with the stringent constraints from the same sign top pair production because of destructive interferences between contributions from the Z' and Higgs boson exchanges.

With an integrated luminosity goal larger than 75 ab-1, the SuperB factory, to be built on the Tor Vergata Campus, near Roma (Italy) by 2016, has the very ambitious goal to unravel the detailed structure of the new physics soon to be discovered at the LHC, or to explore BSM physics beyond the LHC reach if nothing is found there. This goal will be reached using a large number of rare B , charm and tau decays very sensitive to the presence of new heavy particles via virtual loops. The physics prospects of this ultra-high luminosty e+e- collider will be presented in detail as well as the very innovative concepts guiding the machine and detector designs. The important advanatages brought by the specific assets of the SuperB project, namely beam polarization and capability to run at the charm threshold with a significant boost will be presented.

11:00 ORKA, The Golden Kaon Experiment: Precision measurement of K+ -> pi+,nu,nubar and other ultra-rare processes.

Precision measurement of the ultra-rare K+ -> pi+,nu,nubar decay at Fermilab would be one of the most incisive probes of quark flavor physics this decade. This sensitivity is unique in quark flavor physics and allows probing of essentially all models of new physics that couple to quarks within the reach of the LHC. Furthermore, a high precision measurement is sensitive to many models of new physics with mass scales well beyond the direct reach of the LHC. The ORKA initiative aims to precisely measure this process based on established detector techniques driven with the Fermilab Main Injector high intensity proton source. In recognition of this exciting opportunity the Fermilab director has recently granted scientific approval to the ORKA proposal. The experimental technique and prospects will be discussed.

The LHCb experiment is designed to perform high-precision measurements of CP violation and search for New Physics using the enormous flux of beauty and charmed hadrons produced at the LHC. The operation and the results obtained from the data collected in 2010 and 2011 demonstrate that the detector is robust and functioning very well. However, the limit of 1 fb-1 of data per year cannot be overcome without improving the detector. We therefore plan for an upgraded spectrometer by 2018 with a 40 MHz readout and a much more flexible software-based triggering system that will increase the data rate as well as the efficiency specially in the hadronic channels. Here we present the LHCb detector upgrade plans, based on the recently submitted Letter of Intent.
