The Universal Transverse Momentum Dependent Soft Function at NNLO
Miguel G. Echevarria, Ignazio Scimemi, Alexey Vladimirov
All (un)polarized transverse momentum dependent functions (TMDs), both distribution and fragmentation functions, are defined with the same universal soft function, which cancels sp…
Single spin asymmetries from a single Wilson loop
Daniël Boer, Miguel G. Echevarria, Piet Mulders +1
We study the leading-power gluon transverse momentum dependent distributions (TMDs) of relevance to the study of asymmetries in the scattering off transversely polarized hadrons. N…
Perturbative and non-perturbative QCD effects in transverse momentum distributions
Umberto D'Alesio, Miguel G. Echevarria, Stefano Melis +1
The recent formulation of the factorization theorem for transverse momentum spectra in terms of well-defined transverse momentum dependent distributions (TMDs), allows for a better…
The Transverse Momentum Dependent Fragmentation Function at NNLO
Miguel G. Echevarria, Ignazio Scimemi, Alexey Vladimirov
We calculate the unpolarized transverse momentum dependent fragmentation function (TMDFF) at next-to-next-to-leading order (NNLO), evaluating separately TMD soft factor and TMD col…
Effects of TMD evolution and partonic flavor on annihilation into hadrons
Alessandro Bacchetta, Miguel G. Echevarria, Piet J. G. Mulders +2
We calculate the transverse momentum dependence in the production of two back-to-back hadrons in electron-positron annihilations at the medium/large energy scales of BES-III and BE…
Transverse momentum dependent (TMD) parton distribution functions: status and prospects
R. Angeles-Martinez, A. Bacchetta, I. I. Balitsky +34
We provide a concise overview on transverse momentum dependent (TMD) parton distribution functions, their application to topical issues in high-energy physics phenomenology, and th…
QCD evolution of (un)polarized gluon TMDPDFs and the Higgs -distribution
Miguel G. Echevarria, Tomas Kasemets, Piet J. Mulders +1
We provide the proper definition of all the leading-twist (un)polarized gluon transverse momentum dependent parton distribution functions (TMDPDFs), by considering the Higgs boson…
Polarization effects in double open-charm production at LHCb
Miguel G. Echevarria, Tomas Kasemets, Piet J. Mulders +1
Double open-charm production is one of the most promising channels to disentangle single from double parton scattering (DPS) and study different properties of DPS. Several studies…
