$\delta$ meson effects on neutron stars in the modified quark-meson coupling model

open access: yes, 2008
The properties of neutron stars are investigated by including $\delta$ meson field in the Lagrangian density of modified quark-meson coupling model. The $\Sigma^-$ population with $\delta$ meson is larger than that without $\delta$ meson at the beginning,

Excitation Spectrum in the Friedberg-Lee Model [PDF]

open access: yes, 2001
The excitation spectrum of the nucleon with the spin 1/2 is examined by using the Friedberg-Lee model containing the constituent quark and the scalar meson. An appropriate way of quantization for the non-linear meson field is employed by taking account

Free energies as invariants of Teichmüller like structures [PDF]

open access: yes, 2013
A Teichmüller like structure on the space of d-degree holomorphic maps on the circle S1, marked by conjugations to the map z 7→ z d, can be defined. Here we introduce a definition of free energy associated to this kind of dynamics as an invariant of ...

Charm meson scattering cross sections by pion and rho meson [PDF]

open access: yes, 2001
Using the local flavor SU(4) gauge invariance in the limit of vanishing vector meson masses, we extend our previous study of charm meson scattering cross sections by pion and rho meson, which is based only on the pseudoscalar-pseudoscalar-vector meson ...

Racism and racial disparities in firearm violence: A scoping review

open access: yesAmerican Journal of Community Psychology, EarlyView.
Abstract Firearm violence (i.e., interpersonal, police firearm violence) disproportionately affects racially minoritized communities. Researchers recently shifted their focus from race to racism to better understand the factors that contribute to racial disparities in firearm violence.

The non-perturbative unquenched quark model

open access: yesEPJ Web of Conferences, 2017
In recent years states in the quarkonium spectrum not expected in the naive quark model have appeared and created a lot of interest. In the theoretical side the study of the effect of meson-meson thresholds in the spectrum have been performed in ...

(Anti-)Stokes scattering on kinks

open access: yesJournal of High Energy Physics, 2023
At leading order, there are three inelastic scattering processes beginning with a quantum kink and a fundamental meson. Meson multiplication, in which the final state is a kink and two mesons, was treated recently.

Resolving the RpA and v2 puzzle of D0 mesons in p−Pb collisions at the LHC

open access: yesPhysics Letters B, 2023
It has been a challenge to understand the experimental data on both the nuclear modification factor and elliptic flow of D0 mesons in p−Pb collisions at LHC energies.

Effective meson masses, effective meson-nucleon couplings and neutron star radii

open access: yes, 2004
Using the generalized mean field theory, we have studied the relation among the effective meson masses, the effective meson-nucleon couplings and the equation of state (EOS) in asymmetric nuclear matter.
