Double parton distributions in the pion in the Nambu–Jona-Lasinio model

Journal of High Energy Physics, 2019
Two-parton correlations in the pion, a non perturbative information encoded in double parton distribution functions, are investigated in the Nambu–Jona-Lasinio model.

Phases of Hadron-Quark Matter in (Proto) Neutron Stars

Universe, 2019
In the first part of this paper, we investigate the possible existence of a structured hadron-quark mixed phase in the cores of neutron stars. This phase, referred to as the hadron-quark pasta phase, consists of spherical blob, rod, and slab rare phase ...

Octet Magnetic Moments with Null Instantons and Semibosonized Nambu-Jona-Lasinio Model [PDF]

, 1998
It is shown that the difference between the magnetic moment results in the quark model with null instantons and semibosonized Nambu-Jona-Lasinio model lies in the description of the magnetic moment of the $ \Lambda$-hyperon.Comment: RevTex, 6 pages ...

Majorana neutrino and the vacuum of Bogoliubov quasiparticle

Physics Letters B, 2018
The Lagrangian of the seesaw mechanism is C violating but the same Lagrangian when re-written in terms of Majorana neutrinos is manifestly C invariant.

A Multiquark Approach to Excited Hadrons and Regge Trajectories

Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019
We propose a novel approach to construction of hadron spectroscopy. The case of light nonstrange mesons is considered. By assumption, all such mesons above 1 GeV appear due to creation of constituent quark‐antiquark pairs inside π or ρ(ω) mesons. These spin‐singlet or triplet pairs dictate the quantum numbers of formed resonance.

Quark–meson coupling model based upon the Nambu–Jona Lasinio model

Physics Letters B, 2016
The NJL model for the octet baryons, using proper time regularisation to simulate some of the features of confinement, is solved self-consistently in nuclear matter.

The Nambu-Jona-Lasinio model of light nuclei [PDF]

, 2000
The Nambu-Jona-Lasinio model of the deuteron suggested by Nambu and Jona-Lasinio (Phys. Rev. 124 (1961) 246) is formulated from the first principles of QCD. The deuteron appears as a neutron-proton collective excitation, i.e. a Cooper np-pair, induced by

A Guide to Light‐Cone PDFs from Lattice QCD: An Overview of Approaches, Techniques, and Results

Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019
Within the theory of Quantum Chromodynamics (QCD), the rich structure of hadrons can be quantitatively characterized, among others, using a basis of universal nonperturbative functions: parton distribution functions (PDFs), generalized parton distributions (GPDs), transverse momentum dependent parton distributions (TMDs), and distribution amplitudes ...

Comparison of the non-uniform chiral and 2SC phases at finite temperatures and densities [PDF]

, 2006
We study the phase diagram of the strongly interacting matter at finite temperatures and densities including 2SC, uniform chiral and non-uniform chiral phases within the Nambu - Jona-Lasinio model in the mean field approximation.Comment: 11 pages, 4 ...

Direct CP Violation from Isospin Symmetry Breaking Effects for the Decay Process B-s→P(V)π0 in PQCD

Advances in High Energy Physics, Volume 2019, Issue 1, 2019., 2019
We investigate the direct CP violation for the decay process of B-s→P(V)π0 (P,V refer to the pseudoscalar meson and vector meson, resp.) via isospin symmetry breaking effects from the π0 − η − η′ mixing mechanism in PQCD factorization approach. Isospin symmetry breaking arises from the electroweak interaction and the u‐d quark mass difference by the ...
