An N-independent tensor decomposition for SU(N)

Journal of High Energy Physics
To facilitate a simultaneous treatment of an arbitrary number of colors in representation theory-based descriptions of QCD color structure, we derive an N-independent reduction of SU(N) tensor products.

Gravitational form factors of the baryon octet in holographic QCD

Journal of High Energy Physics
The gravitational form factors (GFFs) of the baryon octet, including hyperons, are investigated in a bottom-up holographic QCD model that explicitly incorporates the SU(3) flavor symmetry breaking through the strange quark mass.

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.

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 ...
