Gravitational form factors of hadrons from lattice QCD

open access: yes, 2023
The gravitational form factors (GFFs) of hadrons encode the matrix elements of the energy-momentum tensor of QCD. These quantities describe how energy, spin, and various mechanical properties of hadrons are carried by their quark and gluon constituents ...

Probing transverse momentum dependent structures with azimuthal dependence of energy correlators

open access: yesJournal 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 ...

Inclusive properties of hadronic final states at HERA

open access: yesJournal of Physics: Conference Series, 2008
Recent results from the H1 and ZEUS collaborations using the hadronic final state in high Q2 Deep-Inelastic Scattering to investigate QCD are presented. Measurements of azimuthal asymmetries, event shapes and the charged particle scaled momentum spectra are compared with next-to-leading order perturbative QCD predictions and with Monte Carlo models.

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

open access: yesJournal 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 ...

The baryonic phase in holographic descriptions of the QCD phase diagram

open access: yes, 2012
We study holographic models of the QCD temperature-chemical potential phase diagram based on the D3/D7 system with chiral symmetry breaking. The baryonic phase may be included through linked D5-D7 systems. In a previous analysis of a model with a running

Mechanical properties of proton using flavor-decomposed gravitational form factors

open access: yesJournal of High Energy Physics
We investigate the mechanical properties of the proton by extracting its flavor-decomposed gravitational form factors (GFFs) using Light-Cone QCD sum rules (LCSR).

Masses of hadrons in nuclei

open access: yes, 1998
We emphasize the central role played by the spectral function in the description of hadrons in matter and discuss the applicability of the quasiparticle concept to the propagation of hadrons in dense nuclear matter.

Revising the mass of light hybrid mesons: NLO QCD sum rules point to ϕ(2170) as a prime candidate

open access: yesJournal of High Energy Physics
We present a comprehensive next-to-leading order (NLO) QCD sum rule analysis for light hybrid mesons with J PC = 1 −− , incorporating condensates up to dimension-8 and NLO corrections to the perturbative, gluon condensate, and four-quark condensate ...

Static and dynamic properties of the pion from continuum modelling of strong QCD [PDF]

open access: yes, 2010
We present nonperturbative numerical solutions for the quark propagator Schwinger-Dyson equation (SDE) and pseudoscalar meson Bethe-Salpeter equation (BSE) at and beyond the rainbow-ladder truncation level of this system of equations.

Averages of $b$-hadron, $c$-hadron, and $τ$-lepton properties as of 2023

open access: yes
This paper reports world averages of measurements of $b$-hadron, $c$-hadron, and $τ$-lepton properties obtained by the Heavy Flavour Averaging Group using results available before October 2023. In rare cases, significant results obtained several months later are also used.
