  1. 658. nCTEQ PDFs and the strange PDF at LHC
    Fred Olness (Southern Methodist University (US))
    06/05/2019, 14:15
    parallel talk

    Extraction of the strange quark PDF is a long standing puzzle. We use
    nCTEQ nPDFs with uncertainties to examine W/Z production at the LHC
    and try to study both the nuclear corrections and the flavor
    differentiation. This complements the information from neutrino-DIS
    data. Additionally, we look ahead to future facilities such as EIC,
    LHeC, and LHC upgrades and use a new tool, PDFSense, to...

  2. 735. ePump: error PDF Update Method Package
    Zhite Yu
    06/05/2019, 14:30
    parallel talk

    It is crucial to reduce PDF (Parton Distribution Function) uncertainties in the LHC precision era, so one would be very curious to know what kinds of observables can reduce PDF uncertainties and to what extent. Following this idea, we present a software package ePump, based on Hessian approximation, which can quickly update a set of global-fit PDFs including error PDFs. ePump can reproduce the...

  4. 768. W + jet production at NLO QCD and electroweak accuracy matched to Parton Shower
    Jia Zhou (INFN Sezione di Pavia)
    06/05/2019, 15:00
    parallel talk

    We consider the process of W-boson hadroproduction in association with jets, including leptonic decays of the W boson. We compute the full set of next-to-leading (NLO) corrections at order $\mathcal{O}(\alpha^2\alpha_s^2)$ and $\mathcal{O}(\alpha^3\alpha_s)$ and given by QCD and electroweak corrections to W plus one jet production and QCD corrections to W production in association with a...

  5. 722. Soft gluon radiation of Z boson plus jet production at the LHC
    Dr Bin Yan (Michigan State University )
    06/05/2019, 15:15
    parallel talk

    We study the multiple soft gluon radiation effects in Z boson plus jet production at the LHC. By applying the transverse momentum dependent factorization formalism, the large logarithms introduced by the small total transverse momentum of the Z boson plus jet final state system, are resummed to all orders in the expansion of the strong interaction coupling at the accuracy of Next- to-Leading...

  6. 802. Mixed $QCD\times EW$ double virtual corrections $(O(\alpha \alpha_s))$ to Drell Yan production of W and Z bosons
    Syed Mehedi Hasan (University at Buffalo)
    06/05/2019, 15:30
    parallel talk

    We compute the Mixed $QCD\times EW$ double virtual corrections $(O(\alpha \alpha_s))$ to Drell Yan production of W and Z bosons. We present the explicit analytic results of unrenormalized form factors which are numerically evaluated for different phase space points. For our calculation we used IBP reductions to write the form factors in terms of a handful of master integrals. These master...
