Since the parton model was introduced by Feynman more than 50 years ago, much has
been learned about the partonic structure of the proton through a large body of high-energy …

We highlight the progress, current status, and open challenges of QCD-driven physics, in
theory and in experiment. We discuss how the strong interaction is intimately connected to a …

The rare decays B 0→ K* 0 μ+ μ-and B s→ ϕ μ+ μ-are now being observed with enough
precision to test Standard Model predictions. A full understanding of these decays requires …

We study Euclidean formulations of the transverse-momentum-dependent (TMD) soft
function, which is a cross section for soft gluon radiations involving color charges moving in …

A new method for the model-independent determination of the light-cone distribution
amplitude of the B-meson in heavy quark effective theory (HQET) is proposed by combining …

We present the first lattice QCD determination of the Λ b→ Λ*(1520) vector, axial vector, and
tensor form factors that are relevant for the rare decays Λ b→ Λ*(1520) ℓ+ ℓ-. The lattice …

We present the first lattice-QCD determination of the form factors describing the semileptonic
decays Λ b→ Λ c*(2595) ℓ-ν¯ and Λ b→ Λ c*(2625) ℓ-ν¯, where the Λ c*(2595) and Λ …

We present a determination of the b-quark mass accurate through O (α s 2) in perturbation
theory and including partial contributions at O (α s 3). Nonperturbative input comes from the …

We extract the form factors relevant for semileptonic decays of D and B mesons from a
relativistic computation on a fine lattice in the quenched approximation. The lattice spacing …

A bstract We show that as a result of causality-constrained coordinate space analyticity, the
Drell-Yan-shape transverse-momentum dependent soft factor in the exponential regulator …
