60. Top Quark Mass Measurements

Prof. Stephen Wimpenny (University of California - Riverside), Steve Wimpenny (University of California Riverside (US))

09/05/2016, 14:00

parallel talk

Top quark mass measurements from the CMS experiment at the LHC. The talk will present an overview of the current status of the results from the lepton+jets, dilepton and all-jets channels.

172. Top quark properties and mass measurements with the ATLAS detector

Elizabeth Caitlin Brost (Northern Illinois University (US))

parallel talk

The top quark is unique among the known quarks in that it
decays before it has an opportunity to form hadronic bound
states. This makes measurements of its properties particularly
interesting as one can access directly the properties of a bare
quark. The latest measurements of these properties are
presented. Measurements of the charge asymmetry in top-quark pair,
which probe models of...

86. Top-quark pole mass in the tadpole-free MSbar scheme

Stephen Martin (Northern Illinois University)

parallel talk

The complex pole mass of the top quark is presented at full two-loop order in the Standard Model, augmenting the known four-loop QCD contributions. The input parameters are the MS-bar Yukawa and gauge couplings, the Higgs self-coupling, and the Higgs vacuum expectation value (VEV). Here, the VEV is defined as the minimum of the full effective potential in Landau gauge, so that tadpoles vanish....

This talk is on behalf of the ATLAS Collaboration.

178. Top quark production cross section

Aran Garcia-Bellido (University of Rochester (US))

09/05/2016, 15:00

parallel talk

We will review the latest results from CMS at 13 TeV measuring the production cross section of top pairs and single top.

165. Single Top-Quark Production Cross-Section Measurements Using the ATLAS Detector at the LHC

Oliver Maria Kind (Humboldt-Universitaet zu Berlin (DE))

09/05/2016, 15:15

parallel talk

Abstract.
Measurements of single top-quark production in proton-proton collisions are presented at a centre-of-mass energy of $8\,$TeV and $13\,$TeV. A measurement of the cross-section where a W boson is exchanged in the $t$-channel is discussed and the results for the inclusive production cross-section are presented. A measurement of the production cross-section of a single top quark in...

99. Into this furnace: A heat-proof top charge asymmetry for the LHC

Susanne Westhoff (Heidelberg University)

09/05/2016, 15:30

parallel talk

The abundance of top-quarks at the LHC allows us to test subtle features such as the charge asymmetry in heavy-quark pair production. A promising observable of this fundamental property of QCD is the top-antitop energy asymmetry in jet-associated top-pair production. I will present new predictions of the energy asymmetry beyond the leading order and venture an outlook on the discovery...

147. Probing top-Higgs interactions at NLO accuracy

Cen Zhang (Brookhaven National Laboratory)

09/05/2016, 15:45

parallel talk

I will present some recent progresses and ongoing efforts in developing the SM EFT to next-to-leading order (NLO) accuracy, with a focus on operators involving the top-quark and the Higgs boson fields. Apart from total rate, NLO results matched to the parton shower simulation are also available, allowing for event generation to be directly employed in experimental analyses. Loop-induced...
