چکیده
A bstract Transverse-momentum-dependent parton distributions (TMDs) can be calculated from first principles by computing a related set of Euclidean lattice observables and connecting them via factorization formula. This work focuses on the leading-power formula quasi-TMD continuum Collins TMD for gluons. We calculate one-loop gluon matching coefficient, which is known to independent spin exhibits no mixing with quarks. demonstrate that this coefficient satisfies Casimir scaling respect quark at order. Our result facilitates reliable QCD calculations TMDs.

One Loop Calculation of the Renormalised Anisotropy for Improved Anisotropic Gluon Actions on a Lattice
Using the infrared dispersion relation of the on shell gluon, we calculate the renormali-sation of the the anisotropy, χ, to one loop in perturbation theory for lattice Yang–Mills theories, including the Wilson action and actions with Symanzik and/or tadpole improvement. Using twisted boundary conditions as a gauge invariant infrared regulator, we show for an SU(3) gauge group in D = 3+1 dimens...
متن کاملThe Six Gluon One-Loop Amplitude
The one-loop scattering amplitude for sixgluons in pure QCD has been an interesting test case for the development of analytic techniques in perturbative gauge theories. The amplitude can be decomposed into various subamplitudes which were calculated between 1993 and 2006 [1–13] in thirteen different publications by 23 authors. The results for the amplitude are spread across a large number of pa...

A c++ implementation of the Ds-dimensional unitarity cut algorithm for the numerical evaluation of the virtual contribution to NLO QCD amplitudes is presented. The current version includes an arbitrary number of external gluons with gluonic propagators in the loop. The building blocks are tree level color-ordered amplitudes with gluons and with gluons and two scalars in five dimensions. Numeric...

متن کاملHQET quark - gluon vertex at one loop
We calculate the HQET quark-gluon vertex at one loop, for arbitrary external momenta, in an arbitrary covariant gauge and space-time dimension. Relevant results and algorithms for the three-point HQET integrals are presented. We also show how one can obtain the HQET limit directly from QCD results for the quarkgluon vertex.
