Angular dependence in transverse momentum dependent diffractive parton distributions at small-x
Physics Letters BWe discuss the angular dependence of the recently proposed transverse momentum dependent quark and gluon diffractive parton distributions at small-x. We introduce the diffractive versions of the Sivers function and the elliptic gluon Wigner distribution ...

Gluon condensate and the effective gluon mass
Zeitschrift f�r Physik C Particles and Fields, 1987 Using massive gauge invariant QCD we show explicity how power like corrections to\(\Pi _{\mu v} \left( q \right) = i\int {dx} e^{iq'x} \left\langle {0\left| {j_\mu ^{em} \left( x \right)\bar j_v^{em} \left( 0 \right)} \right|0} \right\rangle \) arise.

Soft Gluon Radiation off Heavy Quarks beyond Eikonal Approximation
Advances in High Energy Physics, 2016 We calculate the soft gluon radiation spectrum off heavy quarks (HQs) interacting with light quarks (LQs) beyond small angle scattering (eikonality) approximation and thus generalize the dead-cone formula of heavy quarks extensively used in the ...

Form factor decompositions of the QCD four - gluon vertex
EPJ Web of Conferences, 2018 The Bern-Kosower formalism, originally developed around 1990 as a novel way of obtaining on-shell amplitudes in field theory as limits of string amplitudes, has recently been shown to be extremely effcient as a tool for obtaining form factor ...

The complex heavy quarkonium potential with the Gribov–Zwanziger action
European Physical Journal C: Particles and FieldsGribov–Zwanziger prescription in Yang–Mills theory improves the infrared dynamics. In this work, we study the static potential of a heavy quark-antiquark pair with the HTL resummed perturbation method within the Gribov–Zwanziger approach at finite ...

Additional moments and x-space approximations of four-loop splitting functions in QCD
Physics Letters BWe have extended our previous computations of the even-N moments of the flavour-singlet four-loop splitting functions to N=12 for the pure-singlet quark case and N=10 for all other cases.

Chiral-odd gluon generalized parton distributions in the proton: A light-front quantization approach
Physics Letters BWithin the basis light-front quantization (BLFQ) framework, we evaluate the gluon chiral-odd generalized parton distributions (GPDs) inside the proton at zero skewness.
