David Martin Bjergaard (Duke University (US))01/09/2015, 16:30Heavy QuarksATLAS has a wide programme to study the production cross section and decay properties of particles with beauty, as well as charmonium and bottomonium states. This presentation will cover ATLAS results in the domain of charmonium production, including J/psi, psi(2s), chi_c and chi_b states as well as the X(3872) resonance, using full Run-1 ATLAS dataset and extending upon previous measurements...Go to contribution page

Jason Adrian Kamin (University of Illinois at Chicago (US))01/09/2015, 16:55Heavy QuarksQuarkonia are important probes of the quark-gluon plasma since they are produced at early times and propagate through the medium, mapping its evolution. In this talk we present the latest results on quarkonium production in pPb and PbPb collisions from CMS. Selected results from measurements of nuclear modification factors, excited-to-ground state ratios, elliptic flow and forward-backward...Go to contribution page

Marco Pappagallo (University of Glasgow (GB))01/09/2015, 17:20Heavy QuarksThe latest results on heavy quark spectroscopy from LHCb experiment will be reported, including the studies on excited bottom and charm mesons and charmonium-like exotic states such as X(3872).Go to contribution page

Konstantin Toms (University of New Mexico (US))01/09/2015, 17:45Heavy QuarksWe present the latest results from the ATLAS experiment on hadron decays and spectroscopy, including observation of the B_c(2S) state, production of the B_c+ meson, branching ratio measurements of B_c->J/psiD(*), extraction of fragmentation fractions fs/fd via reconstructed Bs->J/psiPhi and Bd->J/psiK* decays, and studies of the decay properties of the Lambda_b. We also present the results of...Go to contribution page

Zoltan Laszlo Trocsanyi (University of Debrecen (HU))02/09/2015, 14:10Heavy QuarksWe simulate the hadroproduction of a t tbar pair in association with one or two isolated photons at the LHC using the PowHel program. The generated events are stored according to the Les-Houches event format and constitute an almost inclusive event sample (regarding the photons), so that usual experimental photon isolation can be employed. We interface those events to the PYTHIA shower Monte...Go to contribution page

Katsuya Yamauchi (Nagoya University (JP))02/09/2015, 15:00Heavy QuarksMeasurements of the inclusive top quark pair production cross sections in proton-proton collisions with the ATLAS detector at the Large Hadron Collider are presented. The most precise result requires opposite sign electrons and muons and uses the full data-set at a centre-of-mass energy of 7 and 8 TeV. In addition, differential measurements of the top transverse momentum and kinematic...Go to contribution page

Mark Levy (University of Birmingham (GB))02/09/2015, 15:25Heavy QuarksThe latest measurements of the properties of the top quark using the ATLAS experiment are presented. The top quark mass is one of the fundamental parameters of the Standard Model. A measurement based on a multi-dimensional template fit that can constrain the uncertainties on the energy measurements of jets is presented and combined with a measurement using dilepton events. In addition, novel...Go to contribution page

Steffen Rocker (KIT - Karlsruhe Institute of Technology (DE))02/09/2015, 15:50Heavy QuarksMeasurements are presented of t-channel single top quark production in proton-proton collisions at the LHC at centre-of-mass energies of 7 and 8 !TeV, using data collected with the CMS experiment during the years 2011 and 2012. The analyses consider decay channels where the W from the top decays into electron-neutrino or muon-neutrino, and makes use of kinematic characteristics of electroweak...Go to contribution page

Luminita Mihaila02/09/2015, 16:55Heavy QuarksIn this talk, we are going to report on the recent calculation of the decay rate of the SM Higgs boson to bottom quarks at O(alpha alphas) and discuss its phenomenological implications. In the second part of the talk, we would like to point out the significance of these results in constraining the possible SM extensions.Go to contribution page

Rhorry Graham Gauld02/09/2015, 17:20Heavy QuarksLast year, LHCb performed the first measurement of the angular asymmetry present in bottom-quark pair production at a hadron collider. I will compare the available data to SM predictions, and comment on the potential sensitivity of similar measurements in Run-II. In addition, I will also discuss the feasibility of charm- and top-quark pair asymmetry measurements with Run-II data.Go to contribution page

Fabrizio Margaroli (Universita e INFN, Roma I (IT))02/09/2015, 17:45Heavy QuarksThis talk presents searches for new phenomena in signatures with a pair of top-quarks, a top and bottomquark, together with searches for fermionic top/bottom partners (VLQs). CMS results from Run-1 and Run-2 (if available) will be presented together with their interpretations, with a view to the reconstruction techniques used in the searches.Go to contribution page

Sebastian Pedraza Lopez (Instituto de Fisica Corpuscular (ES))02/09/2015, 18:10Heavy QuarksMeasurements of single top-quark production in proton proton collisions at 7 and 8 TeV are presented. In the leading order process, a W boson is exchanged in the t-channel. The single top-quark and anti-top total production cross sections, their ratio, as well as a measurement of the inclusive production cross section is presented. In addition, a measurement of the production cross section of...Go to contribution page

Minjung Kim (Inha University (KR))04/09/2015, 11:30Heavy QuarksHeavy quarks (charm and beauty) are essential probes of the evolution of the medium created in heavy-ion collisions, because heavy-quark production in high-energy collisions occurs early compared to the formation time of the strongly-interacting partonic matter. To quantify medium effects in AA collisions, one needs to study pp collisions and p-A collisions as references. The measurements of...Go to contribution page

Fabrizio Margaroli (Universita e INFN, Roma I (IT))04/09/2015, 11:55Heavy QuarksIn this talk searches for Higgs bosons produced in association with top quarks are presented. The searches are performed using the data collected during the first LHC run at a center-of-mass energy of 7 and 8 TeV and results are presented for different Higgs decay final states, including bbbar, tautau, WW*/ZZ* and gg, as well as their combination. The talk highlights experimental and...Go to contribution page

Darren Price (University of Manchester (GB))04/09/2015, 12:20Heavy QuarksThe production of heavy flavour jets in association with a vector boson is a process of some importance for searches for new phenomena and precision studies of QCD, which has nonetheless proven difficult to extract and measure in detail. A large and precisely-understood dataset from $p\bar{p}$ collisions at the Tevatron, and the development of techniques at the DZero experiment to isolate the...Go to contribution page
