Published: December 2015

We discuss production of charm and bottom quarks at forward rapidity in collisions at the LHC, updating the QCD predictions for the run at [Formula: see text] TeV. We show that, while the absolute rates suffer from large theoretical systematics, dominated by scale uncertainties, the increase relative to the rates precisely measured at 7 TeV can be predicted with an accuracy of a few percent, sufficient to highlight the sensitivity to the gluon distribution function.

New Data-Driven Constraints on the Sign of Gluon Polarization in the Proton.

Phys Rev Lett

Article Synopsis
  • - The potential existence of negative gluon helicity (Δg) has been found to align with current data from experiments like polarized proton-proton collisions and lattice QCD measurements.
  • - A new analysis of polarized parton distributions in protons introduces constraints from high-x deep-inelastic scattering (DIS).
  • - Results indicate that models incorporating negative Δg struggle to match high-x DIS data alongside other experimental data, implying that negative Δg may not be a viable solution.

Accessing Gluon Parton Distributions in Large Momentum Effective Theory.

Gluon parton distribution functions (PDFs) in the proton can be calculated directly on Euclidean lattices using large momentum effective theory (LaMET). To realize this goal, one has to find renormalized gluon quasi-PDFs in which power divergences and operator mixing are thoroughly understood. For the unpolarized distribution, we identify four independent quasi-PDF correlators that can be multiplicatively renormalized on the lattice.

Gluon Quasi-Parton-Distribution Functions from Lattice QCD.

Phys Rev Lett

December 2018

Department of Physics and Astronomy, University of Kentucky, Lexington, Kentucky 40506, USA.

We present the first attempt to access the x dependence of the gluon unpolarized parton-distribution function (PDF), based on lattice simulations using the large-momentum effective theory approach. The lattice calculation is carried out with pion masses of 340 and 678 MeV on a (2+1)-flavor domain-wall fermion configuration with lattice spacing a=0.111  fm, for the gluon quasi-PDF matrix element with the nucleon momentum up to 0.

The pseudorapidity distributions of dijets as functions of their average transverse momentum (p_{T}^{ave}) are measured in proton-lead (pPb) and proton-proton (pp) collisions. The data samples were collected by the CMS experiment at the CERN LHC, at a nucleon-nucleon center-of-mass energy of 5.02 TeV.

The impact of LHC jet data on the MMHT PDF fit at NNLO.

Eur Phys J C Part Fields

We investigate the impact of the high precision ATLAS and CMS 7 TeV measurements of inclusive jet production on the MMHT global PDF analysis at next-to-next-to-leading order (NNLO). This is made possible by the recent completion of the long-term project to calculate the NNLO corrections to the hard cross section. We find that a good description of the ATLAS data is not possible with the default treatment of experimental systematic errors, and propose a simplified solution that retains the dominant physical information of the data.
