Nucleon Structure Functions from ν_µ-Fe Interactions and a Study of the Valence Quark Distribution [PDF]
, 1984 Data were taken in 1979-80 by the CCFRR high energy neutrino experiment at Fermilab. A total of 150,000 neutrino and 23,000 antineutrino charged current events in the approximate energy range 25 < Ev < 250 GeV are measured and analyzed.

Effective locality and gauge invariance
EPJ Web of Conferences, 2018 A few years ago, based on standard functional manipulations, an unexpected property was proven to be satisfied by the fermionic Green's functions of QCD, and dubbed effective locality.

MS renormalization of S-wave quarkonium wavefunctions at the origin
Journal of High Energy Physics, 2020 We compute S-wave quarkonium wavefunctions at the origin in the MS ¯ $$ \overline{\mathrm{MS}} $$ scheme based on nonrelativistic effective field theories.

m‾c and m‾b from MBc and improved estimates of fBc and fBc(2S)
Physics Letters B, 2020 We extract (for the first time) the correlated values of the running masses m‾c and m‾b from MBc using QCD Laplace sum rules (LSR) within stability criteria where perturbative (PT) expressions at N2LO and non-perturbative (NP) gluon condensates at LO are

Perturbative QCD and tau decay [PDF]
Nuclear Physics B - Proceedings Supplements, 1997 Sufficiently inclusive observables in the decay of the tau lepton can be calculated using the methods of perturbative QCD. These include the asymmetry parameter $A_τ$ that determines that angular distribution of the total hadron momentum in the decay of a polarized tau.

Master integrals for two-loop QCD corrections to quark quasi PDFs
Journal of High Energy Physics, 2020 We compute the master integrals for the two-loop QCD corrections to quark quasi parton distribution functions (PDFs) in the large momentum effective theory (LaMET). With a proper canonical basis, we derive the analytical results for the three families of

Soft-drop grooming for hadronic event shapes
Journal of High Energy Physics, 2021 Soft-drop grooming of hadron-collision final states has the potential to significantly reduce the impact of non-perturbative corrections, and in particular the underlying-event contribution.

The two-loop perturbative correction to the (g − 2) μ HLbL at short distances
Journal of High Energy Physics, 2021 The short-distance behaviour of the hadronic light-by-light (HLbL) contribution to (g − 2) μ has recently been studied by means of an operator product expansion in a background electromagnetic field.
