A comparative analysis of Mesonic, Baryonic and Glueball Regge trajectories

Abstract

We present a comparative analysis of mesonic, baryonic and Glueball Regge trajectories based on different parameters. The different inbuilt compositions of the three seem to serve as a basis for their individual identities. We discuss features such as crossed channel forces, signature, string models and also the dependence of the slope of the mesons and baryons on the fine structure constant. We infer that inspite of various inherent similarities, these three Regge trajectories have some distinctive features which serve as a basis for their identification.

AdS 5 black hole at $$\mathcal{N}=2$$ N = 2 supergravity

“…We know that the imaginary part of the Green's function is used to obtain the quasinormal modes [17]. In order to find the quasi-normal modes various methods have been used [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. For the first time in this paper, we consider the problem of charged non-extremal AdS 5 black hole at the N = 2 supergravity background and study various thermodynamical aspect of this theory.…”
