Diphoton production at the LHC: a QCD study up to NNLO

Journal of High Energy Physics, 2018
We consider the production of prompt-photon pairs at the LHC and we report on a study of QCD radiative corrections up to the next-to-next-to-leading order (NNLO). We present a detailed comparison of next-to-leading order (NLO) results obtained within the

Recent Low x and Diffractive Collider Data

, 2000
Selected recent data from collider experiments pertaining to the understanding of QCD at low Bjorken-x are reviewed. The status of QCD and Regge factorisation in hard diffractive interactions is discussed in terms of data from HERA and the Tevatron.

Global QCD Analysis and Collider Phenomenology--CTEQ

, 2007
An overview is given of recent progress on a variety of fronts in the global QCD analysis of the parton structure of the nucleon and its implication for collider phenomenology, carried out by various subgroups of the CTEQ collaboration.

QCD Phenomenology and Light-Front Wavefunctions [PDF]

, 2001
A natural calculus for describing the bound-state structure of relativistic composite systems in quantum field theory is the light-front Fock expansion which encodes the properties of a hadrons in terms of a set of frame-independent n-particle wavefunctions.

Zγ production at NNLO including anomalous couplings

Journal of High Energy Physics, 2017
In this paper we present a next-to-next-to-leading order (NNLO) QCD calculation of the processes pp → l + l −γ and pp→νν¯γ $$ pp\to \nu \overline{\nu}\gamma $$ that we have implemented in MCFM.

Perspectives and Challenges for QCD Phenomenology [PDF]

, 2001
A fundamental understanding of quantum chromodynamics, particularly at the amplitude level, is essential for progress in high energy physics. For example, the measurement and interpretation of the basic parameters of the electroweak theory and CP violation depends on an understanding of the dynamics and phase structure of exclusive B-meson decay ...

Transverse momentum spectrum of dilepton pair in the unpolarized π− N Drell-Yan process within TMD factorization

Journal of High Energy Physics, 2017
We study the transverse momentum spectrum of dilepton produced in the unpolarized π− N Drell-Yan process, using transverse momentum dependent factorization up to next-to-logarithmic order of QCD. We extract the nonperturbative Sudakov form factor for the

Gauge-invariant Mass Terms and Wave Functions

, 2012
We outline a method of relating the quantum effective action and the ground state wave function of a field theory. This method, along with a gauge-invariant mass term and the previously obtained vacuum wave function, is used to arrive at the leading ...

From QCD Phenomenology to Nuclear Physics Phenomenology: The Chiral Confining Model

Symmetry
We present a theoretical framework that allows one to make an explicit connection between the phenomenology of QCD, namely the properties of the gluon correlator and Wilson loops, and a particular relativistic model for the description of nuclear matter and neutron stars: the chiral confining model.
