Heavy and light quarks in the instanton vacuum
EPJ Web of Conferences, 2012 Assuming the gluon field is well approximated by instanton configurations we derive a light quarks determinant and calculate its contribution to the specific heavy quarks correlators – namely, the heavy quark propagator and heavy quark-aniquark ...

Heavy-heavy and heavy-light quarks interactions generated by QCD vacuum
EPJ Web of Conferences, 2017 The QCD vacuum is populated by instantons that correspond to the tunneling processes in the vacuum. This mechanism creates the strong vacuum gluon fields.

Um modelo teórico para o cálculo do raio do próton [PDF]
Revista Brasileira de Ensino de Física, 2021 Medir o raio do próton oferece informações a respeito de sua estrutura interna, de modo que medidas utilizando diferentes métodos foram realizadas ao longo da história. Contudo, em 2010 uma nova medida diferindo 4% das anteriores gerou o problema chamado

Time-dependent study of K S → π + π − decays for flavour physics measurements
Journal of High Energy Physics, 2021 Nowadays High Energy Physics experiments can accumulate unprecedented statistics of heavy flavour decays that allows to apply new methods, based on the study of very rare phenomena, which used to be just desperate.

Unconventional Mechanisms of Heavy Quark Fragmentation
Universe, 2023 Heavy and light quarks produced in high-pT partonic collisions radiate differently. Heavy quarks regenerate their color field, stripped-off in the hard reaction, much faster than the light ones and radiate a significantly smaller fraction of the initial ...

A Flavorful Top-Coloron Model [PDF]
, 2013 In this paper we introduce a simple renormalizable model of an extended color gauge sector in which the third-generation quarks couple differently than the lighter quarks. In addition to a set of heavy color-octet vector bosons (colorons), the model also

Effects of finite coverage on global polarization observables in heavy ion collisions
Physics Letters B, 2018 In non-central relativistic heavy ion collisions, the created matter possesses a large initial orbital angular momentum. Particles produced in the collisions could be polarized globally in the direction of the orbital angular momentum due to spin–orbit ...

Parton Distribution Functions in the CTEQ framework
Dera Natung Government College Research Journal, 2020 Parton distribution functions (PDFs) are important to study the structure of the proton and hence the dynamics of quarks and gluons inside it. We study some of the PDFs from global CTEQ (Coordinated Theoretical-Experimental project on QCD) analysis in a ...

Recent MILC spectrum results [PDF]
, 1996 We report on results from three spectrum calculations with staggered quarks: 1) a quenched calculation with the standard action for the gluons and quarks; 2) a quenched calculation with improved actions for both the gluons and quarks; and 3) a ...

Flavor ordering of elliptic flows at high transverse momentum [PDF]
, 2002 Based on the quark coalescence model for the parton-to-hadron phase transition in ultra-relativistic heavy ion collisions, we relate the elliptic flow ($v_2$) of high $\pt$ hadrons to that of high $\pt$ quarks.
