Unveiling the Collins-Soper kernel in inclusive DIS at threshold
Andrea Simonelli, Alberto Accardi, Matteo Cerutti +2
We revisit the factorization of inclusive deep inelastic scattering near the kinematic threshold to explicitly track off-lightcone effects. Particle production develops around two…
Partial-wave projection of relativistic three-body amplitudes
Raúl A. Briceño, Caroline S. R. Costa, Andrew W. Jackura
We derive the integral equations for partial-wave projected three-body scattering amplitudes, starting from the integral equations for three-body amplitudes developed for lattice Q…
Hadronization dynamics from the spectral representation of the gauge invariant quark propagator
Caroline S. R. Costa, Alberto Accardi, Andrea Signori
Using the spectral representation of the quark propagator we study the Dirac decomposition of the gauge invariant quark propagator, whose imaginary part describes the hadronization…
Gauge invariant spectral analysis of quark hadronization dynamics
Alberto Accardi, Caroline S. R. Costa, Andrea Signori
We study the Dirac decomposition of the gauge invariant quark propagator, whose imaginary part describes the hadronization of a quark as this interacts with the vacuum, and relate…
Intrinsic Glue and Wilson lines within Dressed Quarks
C. S. R. Costa, Adam Freese, Ian C. Cloët +3
We construct a quark target model (QTM) to incorporate intrinsic glue into effective low-energy models of QCD, which often contain only quark degrees of freedom. This method guaran…
Quark propagator in Minkowski space
E. L. Solis, C. S. R. Costa, V. V. Luiz +1
The analytic structure of the quark propagator in Minkowski space is more complex than in Euclidean space due to the possible existence of poles and branch cuts at timelike momenta…
