Transverse Λ polarization in e + e − processes within a TMD factorization approach and the polarizing fragmentation function

Journal of High Energy Physics, 2022
We perform a re-analysis of Belle data for the transverse Λ and Λ ¯ $$ \overline{\Lambda} $$ polarization in e + e − annihilation processes within a transverse momentum dependent (TMD) factorization approach.

Experimental Targets for Photon Couplings of the QCD Axion

, 2018
The QCD axion's coupling to photons is often assumed to lie in a narrow band as a function of the axion mass. We demonstrate that several simple mechanisms, in addition to the photophilic clockwork axion already in the literature, can significantly ...

Recent progress in QCD calculations for e^+e^- annihilation and hadron collisions [PDF]

, 2011
We provide a brief summary of recent developments in QCD calculations in and beyond fixed-order perturbation theory, for observables in $e^{+}e^{-}$ annihilation as well as hadron collisions.Comment: 9 pages, invited review talk at the meeting LC 10 ...

Isotensor Axial Polarizability and Lattice QCD Input for Nuclear Double-β Decay Phenomenology. [PDF]

Physical Review Letters, 2017
The potential importance of short-distance nuclear effects in double-β decay is assessed using a lattice QCD calculation of the nn→pp transition and effective field theory methods.

"Nonbaryonic" Dark Matter as Baryonic Color Superconductor

, 2003
We discuss a novel cold dark matter candidate which is formed from the ordinary quarks during the QCD phase transition when the axion domain wall undergoes an unchecked collapse due to the tension in the wall.

Quark polarization and transverse momentum effects on double quarkonium production in hadronic collisions

Journal of High Energy Physics
We investigate the inclusive production of double quarkonia (J/ψ, ψ(2S), Υ mesons) in polarized hadron-hadron collisions, considering the kinematic configuration where the transverse momentum of each pair of bound states is much smaller than its ...

Full treatment of the thrust distribution in single inclusive e + e − → h X processes

Journal of High Energy Physics, 2023
Extending the transverse momentum dependent factorization to thrust dependent observables entails a series of difficulties, ultimately associated to the behavior of soft radiation.

The Higgs transverse momentum distribution in gluon fusion as a multiscale problem [PDF]

, 2015
We consider Higgs production in gluon fusion and in particular the prediction of the Higgs transverse momentum distribution. We discuss the ambiguities affecting the matching procedure between fixed order matrix elements and the resummation to all orders

National software infrastructure for lattice quantum chromodynamics

, 2006
Quantum chromodynamics (QCD) is the widely accepted theory of the strong interactions of quarks and gluons. Only through large scale numerical simulation has it been possible to work out the predictions of this theory for a vast range of phenomena ...
