Um modelo teórico para o cálculo do raio do próton [PDF]
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
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
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 ...

Effects of finite coverage on global polarization observables in heavy ion collisions
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
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 ...

Quark Deconfinement in Rotating Neutron Stars
In this paper, we use a three flavor non-local Nambu–Jona-Lasinio (NJL) model, an improved effective model of Quantum Chromodynamics (QCD) at low energies, to investigate the existence of deconfined quarks in the cores of neutron stars.

The Structure of the Hadron-Quark Combustion Zone
Hadron-quark combustion in dense matter is a central topic in the study of phases in compact stars and their high-energy astrophysics. We critically reviewed the literature on hadron-quark combustion, dividing them into a “first wave” that ...

Proton internal pressure distribution suggests a simple proton structure
Understanding the origin of quark confinement in hadrons remains one of the most challenging problems in modern physics. Recently, the pressure distribution inside the proton was measured via deeply virtual Compton scattering.
