Constituent quark masses obtained from hadron masses with contributions of Fermi-Breit and Glozman-Riska hyperfine interactions
V. Borka Jovanović, S. R. Ignjatović, D. Borka +1
We use the color-spin and flavor-spin interaction Hamiltonians with SU(3) flavor symmetry breaking to obtain meson and baryon mass formulas. Adjusting these masses with experimenta…
RXJ 0921+4529: a binary quasar or gravitational lens?
L. Č. Popović, A. V. Moiseev, E. Mediavilla +4
We report the new spectroscopic observations of the gravitational lens RXJ 021+4529 with the multi-mode focal reducer SCORPIO of the SAO RAS 6-m telescope. The new spectral observa…
Variability of the H-beta line profiles as an indicator of orbiting bright spots in accretion disks of quasars: a case study of 3C 390.3
P. Jovanović, L. Č. Popović, M. Stalevski +1
Here we show that in the case when double peaked emission lines originate from outer parts of accretion disk, their variability could be caused by perturbations in the disk emissiv…
