All-gluon amplitudes with off-shell recursion in multiplet bases

Journal of High Energy Physics
The efficient computation of color-summed QCD amplitudes at high parton multiplicities remains a central challenge for precision collider predictions.

The electromagnetic form factors of heavy-light pseudo-scalar and vector mesons

Journal of High Energy Physics
We systematically investigate the electromagnetic form factors of heavy-light pseudo-scalar and vector mesons within the Dyson-Schwinger/Bethe-Salpeter equations framework for the first time.

Probing transverse momentum dependent structures with azimuthal dependence of energy correlators

Journal of High Energy Physics
We study the azimuthal angle dependence of the energy-energy correlators $$\langle \mathcal{E}\left({\widehat{n}}_{1}\right)\mathcal{E}\left({\widehat{n}}_{2}\right)\rangle $$ in the back-to-back region for e + e − annihilation and deep inelastic ...

Simplifying QCD event generation with chirality flow, reference vectors and spin directions

Journal of High Energy Physics
The chirality-flow formalism, combined with good choices of gauge reference vectors, simplifies tree-level calculations to the extent that it is often possible to write down amplitudes corresponding to Feynman diagrams immediately.

Automated computation of spin-density matrices and quantum observables for collider physics

Journal of High Energy Physics
We present a fully automated framework to compute production spin-density matrices for generic collider processes at tree level within MadGraph5_aMC@NLO. The method assembles helicity amplitudes into event-by-event production matrices.

Quarkonium parton shower in Herwig 7

Journal of High Energy Physics
We present the implementation of a fully automated quarkonium parton shower in Herwig 7, based on non-relativistic QCD (NRQCD) factorisation with spin-colour projections.
