Lattice QCD at the end of 2003

, 2003
I review recent developments in lattice QCD. I first give an overview of its formalism, and then discuss lattice discretizations of fermions. We then turn to a description of the quenched approximation and why it is disappearing as a vehicle for QCD ...

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 ...

Phenomenology on the QCD dipole picture revisited

, 2003
We perform an adjust to the most recent structure function data, considering the QCD dipole picture applied to ep scattering. The structure function F2 at small x and intermediate Q2 can be described by the model containing an economical number of free ...

Transforming differential equations of multi-loop Feynman integrals into canonical form

Journal of High Energy Physics, 2017
The method of differential equations has been proven to be a powerful tool for the computation of multi-loop Feynman integrals appearing in quantum field theory.

Top-quark pair hadroproduction at NNLO: differential predictions with the MS ¯ $$ \overline{\mathrm{MS}} $$ mass

Journal of High Energy Physics, 2020
We consider top-quark pair production at the LHC within the MS ¯ $$ \overline{\mathrm{MS}} $$ scheme for the renormalisation of the top-quark mass, and we present predictions for total and differential cross sections at next-to-next-to-leading order ...

Holographic like models as a five-dimensional rewriting of large-Nc QCD

, 2010
The AdS/QCD models are known to be tightly related with the QCD sum rules in the large-Nc (called also planar) limit. Rewriting the theory of infinite tower of free stable mesons expected in the large-Nc QCD as a five-dimensional theory we scrutinize to ...

Precision phenomenology with MCFM

Journal of High Energy Physics, 2019
Without proper control of numerical and methodological errors in theoretical predictions at the per mille level it is not possible to study the effect of input parameters in current hadron-collider measurements at the required precision.

Dense QCD and phenomenology of compact stars [PDF]

, 2013
I discuss three topics in physics of massive (two solar-mass and larger) neutron stars containing deconfined quark matter: (i) the equation of state of deconfined dense quark matter and its color superconducting phases, (ii) the thermal evolution of ...
