QCD for Collider Physics

, 2011
These lectures are directed at a level suitable for graduate students in experimental and theoretical High Energy Physics. They are intended to give an introduction to the theory and phenomenology of quantum chromodynamics (QCD) as it is used in collider

Probing axial quark generalized parton distributions through exclusive photoproduction of a γπ ± pair with a large invariant mass

Journal of High Energy Physics, 2018
Exclusive photoproduction of a γπ ± pair in the kinematics where the pair has a large invariant mass and the final nucleon has a small transverse momentum is described in the collinear factorization framework.

Hadroproduction of scalar P -wave quarkonia in the light-front k T -factorization approach

Journal of High Energy Physics, 2020
In this work, we present a thorough analysis of scalar P -wave χ Q0, Q = c, b quarkonia electromagnetic form factors for the γ ∗ γ ∗ → χ Q0 couplings, as well as their hadroproduction observables in k ⊥-factorisation using the light-front (LF) potential ...

Studies of Light Scalar Particles and Dressed Gauge Propagators in QCD [PDF]

, 2010
The equations of QCD are widely believed to describe the properties of mesons, baryons and their hadronisation after hard interactions at particle accelerators such as the LHC.

Assuming Regge trajectories in holographic QCD: from OPE to Chiral Perturbation Theory [PDF]

, 2015
The soft wall model in holographic QCD has Regge trajectories but wrong operator product expansion (OPE) for the two-point vectorial QCD Green function. We modify the dilaton potential to comply OPE.

Impact of isolation and fiducial cuts on q T and N-jettiness subtractions

Journal of High Energy Physics, 2020
Kinematic selection cuts and isolation requirements are a necessity in experimental measurements for identifying prompt leptons and photons that originate from the hard-interaction process of interest.

NNLO QCD corrections to leptonic observables in top-quark pair production and decay

Journal of High Energy Physics, 2021
We calculate a comprehensive set of spin correlations and differential distributions in top-quark pair production and decay to dilepton final states. Our calculation is performed in the Narrow Width Approximation.

Isolated photon and photon+jet production at NNLO QCD accuracy

Journal of High Energy Physics, 2020
We describe the calculation of the next-to-next-to-leading order (NNLO) QCD corrections to isolated photon and photon-plus-jet production, and discuss how the experimental hadron-level photon definition and isolation criteria can be approximated in the ...

HERWIG 6: an event generator for Hadron emission reactions with interfering gluons (including supersymmetric processes)

, 2000
HERWIG is a general-purpose Monte Carlo event generator, which includes the simulation of hard lepton-lepton, lepton-hadron and hadron-hadron scattering and soft hadron-hadron collisions in one package. It uses the parton-shower approach for initial- and

Signals of the QCD Phase Transition in the Heavens

, 2007
The modern phase diagram of strongly interacting matter reveals a rich structure at high-densities due to phase transitions related to the chiral symmetry of quantum chromodynamics (QCD) and the phenomenon of color superconductivity.
