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 ...

A convergent reformulation of perturbative QCD [PDF]

, 2000
We present and explore a new formulation of perturbative QCD based not on the renormalised coupling but on the dimensional transmutation parameter of the theory and the property of asymptotic scaling.

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.

Bypassing spin-analyzing power dependence for quantum entanglement at colliders: a case study of Λ Λ ¯ $$ \Lambda \overline{\Lambda} $$

Journal of High Energy Physics
We study, as a concrete case study using the Λ → p π − Λ ¯ → p ¯ π + $$ \Lambda \left(\to p{\pi}^{-}\right)\overline{\Lambda}\left(\to \overline{p}{\pi}^{+}\right) $$ system, whether quantum entanglement in fermion pairs produced at colliders can be ...

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.
