Intrinsic bottom and its impact on heavy new physics at the LHC

open access: yesEPJ Web of Conferences, 2016
Heavy quark parton distribution functions (PDFs) play an important role in several Standard Model and New Physics processes. Most analyses rely on the assumption that the charm and bottom PDFs are generated perturbatively by gluon splitting and do not ...

Recent Progress in Heavy Quark Physics [PDF]

open access: yesLepton-Photon 01, 2001
Some of the recent progress in heavy quark physics is reviewed. Special attention is paid to inclusive methods for determining Vub and factorization in nonleptonic B decays.

Heavy Quark Physics From Lattice QCD [PDF]

open access: yes, 1997
We review the application of lattice QCD to the phenomenology of b- and c-quarks. After a short discussion of the lattice techniques used to evaluate hadronic matrix elements and the corresponding systematic uncertainties, we summarise results for ...

QCD at the amplitude level: Fock state interference in heavy quark electroproduction

open access: yesJournal of High Energy Physics, 2023
Quantum chromodynamics (QCD) rigorously predicts the existence of both nonperturbative intrinsic and perturbative extrinsic heavy quark contents of nucleons.

QCD light-cone distribution amplitudes of heavy mesons from boosted HQET

open access: yesJournal of High Energy Physics, 2023
Light-cone distribution amplitudes (LCDAs) frequently arise in factorization theorems involving light and heavy mesons. The QCD LCDA for heavy mesons includes short-distance physics at energy scales of the heavy-quark mass.

A fragmentation-based study of heavy quark production

open access: yesJournal of High Energy Physics, 2020
Processes involving heavy quarks are a crucial component of the LHC physics program, both by themselves and as backgrounds for Higgs physics and new physics searches. In this work, we critically reconsider the validity of the widely-adopted approximation

Heavy Quark Physics [PDF]

open access: yes, 2000
Understanding the physics of heavy quarks gives physicists the unique opportunity to test the predictions of Quantum Chromodynamics and the Standard Model. First published in 2000, this introductory text on this exciting area of high-energy physics begins with a review of the standard model, followed by the basics of heavy quark spin-flavor symmetry ...

Heavy-quark spin symmetry breaking in the Born-Oppenheimer approximation

open access: yesJournal of High Energy Physics, 2023
Heavy-quark spin symmetry is explicitly broken by the mass splitting between a heavy-light pseudoscalar meson and its vector partner. This fact plays a pivotal role in the physics of states whose mass lies close to the threshold of an open-flavor meson ...

Dedication to Nathan Isgur [PDF]

open access: yes, 2002
Nathan passed away in July after a lengthy illness. I am sure most of you are familiar with his many contributions to heavy quark physics and it is certainly fitting that we take a few minutes to honor him at the beginning of this meeting.
