The rings of (2060) Chiron: Evidence of an evolving system

C. L. Pereira, F. Braga-Ribas, B. Sicardy +54

The centaur (2060) Chiron has long been a candidate for hosting material in orbit, based on occultation and photometric and spectroscopic data. Here, we present a multichord stella…

Nucleon Electromagnetic and Axial Form Factors in a Light-front Constituent Quark Model

W. R. B. de Araújo, E. F. Suisso, J. P. B. C. de Melo +2

In the present work we study the effect of the scalar spin coupling of constituent quarks on the nucleon electroweak properties by introducing a valence light-front wave function w…

Analytical warm dark matter power spectrum on small scales

G. Pordeus-da-Silva, R. C. Batista, L. G. Medeiros

Using the Reduced Relativistic Gas (RRG) model, we analytically determine the matter power spectrum for Warm Dark Matter (WDM) on small scales, . The RRG is a si…

Study of the in-medium nucleon electromagnetic form factors using a light-front nucleon wave function combined with the quark-meson coupling model

W. R. B. de Aráujo, J. P. B. C. de Melo, K. Tsushima

We study the nucleon electromagnetic (EM) form factors in symmetric nuclear matter as well as in vacuum within a light-front approach using the in-medium inputs calculated by the q…
