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 ...

Mechanical properties of proton using flavor-decomposed gravitational form factors

Journal 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).

Quark charge balance function and hadronization effects in relativistic heavy ion collisions

, 2012
We calculate the charge balance function of the bulk quark system before hadronization and those for the directly produced and the final hadron system in high energy heavy ion collisions.

Hyperon semileptonic decays in QCD sum rules

Journal of High Energy Physics
We investigate the hyperon semileptonic decays within the framework of QCD sum rules. The flavor SU(3) symmetry breaking effects are analyzed via the relevant form factors and corresponding branching fractions.

Hadrons with Two Heavy Quarks

, 1994
We review the spectroscopy and some properties of hadrons containing two charmed quarks, or more generally, two heavy quarks. This includes heavy baryons such as $(bcu)$, and possible exotic multiquark states.Comment: Talk given at the CHARM 2000 ...

Hadron Properties in the Vicinity of $T_c$

, 1994
Modifications of hadron masses and some of their basic properties with temperature or nuclear density are considered as one possible signature for the formation of dense hadronic matter in nuclear collisions. We discuss here some basic results on the temperature dependence of hadron properties obtained from calculations of hadron correlation functions,

Exploring Efimov states in D * D * D * and DD * D * three-body systems

Journal of High Energy Physics
The Efimov effect is an intriguing three-body quantum phenomenon. Searching for Efimov states within the realms of nuclear and hadronic physics presents a challenge due to the inherent inability of natural physical systems to exhibit adjustable two-body ...

The ρ(770, 1450) → ωπ contributions for three-body decays B → D ¯ ∗ ωπ $$ B\to {\overline{D}}^{\left(\ast \right)}\omega \pi $$

Journal of High Energy Physics
The decays B → D ¯ ∗ ωπ $$ B\to {\overline{D}}^{\left(\ast \right)}\omega \pi $$ are very important for the investigation of ρ excitations and the test of factorization hypothesis for B meson decays. The B + → D ¯ ∗ 0 ω π + $$ {B}^{+}\to {\overline{D}}^{\

Z c and Z cs systems with operator mixing at NLO in QCD sum rules

Journal of High Energy Physics
We study the mass spectra of hidden-charm tetraquark systems with quantum numbers (I G )J P = (1+)1+ (and their I = 1 2 $$ \frac{1}{2} $$ partners) using QCD sum rules.

On the Energy Budget of Quarks and Hadrons, Their Inconspicuous “Strong Charge”, and the Impact of Coulomb Repulsion on the Charged Ground States

Particles
We review and meta-analyze particle data and properties of hadrons with measured rest masses. The results of our study are summarized as follows. (1) The strong-force suppression of the repulsive Coulomb forces between quarks is sufficient to explain the
