Gauge-invariant Mass Terms and Wave Functions

open access: yes, 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 ...

Multiplicity and Underlying Event in ALICE: as measurements and as tools to probe QCD

open access: yes, 2018
With the high collision energies at the LHC, the contributions to particle production from hard-QCD processes increase, but it remains dominated by soft-QCD processes.

Understanding forward B hadron production

open access: yesJournal of High Energy Physics, 2017
The LHCb collaboration has recently performed a measurement of the production rate of inclusive B hadron production (pp → BX) at both 7 and 13 TeV centre-of-mass (CoM) energies.

Gauge-invariant quark and gluon fields in QCD: dynamics, topology, and the Gribov ambiguity

open access: yes, 2001
We review the implementation, in a temporal-gauge formulation of QCD, of the non-Abelian Gauss's law and the construction of gauge-invariant gauge and matter fields.

Progress in QCD Using Lattice Gauge Theory

open access: yes, 1993
Review of results from lattice QCD of relevance to standard-model phenomenology, to appear in Annual Review of Nuclear and Particle Science. KEY WORDS: hadron masses, quark mixing (CKM) matrix, weak matrix elements, strong coupling constant.Comment: 41 ...

BFKL Pomeron loop contribution in diffractive photoproduction and inclusive hadroproduction of J/ψ and ϒ

open access: yesJournal of High Energy Physics, 2019
We analyze contributions to the heavy vector meson production with large transverse momentum in proton-proton and diffractive photon-proton scattering driven by an exchange of two Balitsky-Fadin-Kuraev-Lipatov Pomerons in the squared amplitudes.

Revisiting B → ππℓν at large dipion masses

open access: yesJournal of High Energy Physics, 2018
We revisit QCD factorization of B → ππ form factors at large dipion masses, by deriving new constraints based on the analyticity properties of these objects.
