15. Deconfinement and Equation of State in QCD

Peter Petreczky (BNL)

08/10/2015, 09:00

Status of QCD

Oral Presentation

I will review the current status of equation of state calculations and deconfinement transition in 2+1 flavor QCD obtained using lattice calculations. I will discuss aspects of deconfinement related to fluctuations of conserved charges and screening of color charges in the deconfined medium using expectation value of Polyakov loop and Polyakov loop correlators.

105. Heavy quark masses from lattice QCD.

Dr Andrew Lytle (University of Glasgow)

Status of QCD

Oral Presentation

I will review progress in quark mass determinations from lattice QCD simulation, focusing on results for charm and bottom mass. These are of particular interest for precision Higgs studies. Recent determinations have achieved percent-level uncertainties with controlled systematics. Future prospects for these calculations will also be discussed.

67. Recent results on hadron structure observables using lattice QCD simulations

Alexandrou Constantia (University of Cyprus and The Cyprus Institute)

Status of QCD

Oral Presentation

We give an overview of recent results on hadron structure observables using lattice QCD simulations with physical values of the quark masses.

50. Parton distribution functions and the structure of the proton: the CT14 QCD global analysis

Dr Marco Guzzi (University of Manchester)

08/10/2015, 10:15

Status of QCD

Oral Presentation

An overview on the new parton distribution functions (PDFs) up to next-to-next-to-leading order (NNLO) from the CTEQ-TEA global analysis of quantum chromodynamics will be given. Predictions for important LHC processes, especially Higgs boson and top-quark pair production at 7, 8, 13 TeV, will be presented, and main features and impact of CT14 PDFs on LHC physics will be discussed.

126. Theory status of jet physics

Prof. Andre Hoang (Univ. of Vienna)

08/10/2015, 11:00

104. Overview of QCD measurements at high pT

Matthias Weber (University of California Los Angeles (UCLA))

08/10/2015, 11:25

Status of QCD

Oral Presentation

This talk gives an overview of QCD measurements at high pT at the LHC and other colliders. Recent results on inclusive jet, dijet and multijet production measurements are presented together with results of alpha_S extraction and constraints on the PDFs of the proton. Precision measurements of vector bosons (V = W, Z or γ) in association with jets allow for stringent tests of perturbative QCD....

16. Determination of alpha_s from the QCD static energy

Antonio Vairo (TU Munich)

08/10/2015, 11:50

Status of QCD

Oral Presentation

We present the latest determination of the strong-coupling constant from the quantum chromodynamics static energy. It comes from comparing three-loop perturbative QCD with 2+1 unqueched lattice data and provides up to date one of the most accurate low-energy determinations of alpha_s.

127. The 2015 World Summary of alpha_s

Prof. S. Bethke (Max Planck Institute für Physik)

08/10/2015, 12:15

Status of QCD

Oral Presentation

A preliminary preview will be given on the recent update of alpha_s measurements and the new world average value of alpha_s(M_z), which is currently prepared for the 2015 edition of PDG's Review of Particle Properties.
