Spectroscopy, Regge trajectories and decay properties of the \(bc\bar q\bar q\) and \(bq\bar c\bar q\) tetraquark systems
Chetan Lodha, Ajay Kumar Rai
Bottom-charm tetraquarks probe the interplay of heavy-quark dynamics, light-quark correlations, color structure and nearby hadronic thresholds. We investigate the spectroscopy and…

Spectroscopy of , , and pentaquarks within the framework of Regge phenomenology
Vandan Patel, Ajay Kumar Rai
We investigate the mass spectra of the \(ncnc\bar{c}\), \(nnnn\bar{c}\), and \(nnnc\bar{c}\) pentaquark systems, where \(n\) denotes a light \(u\) or \(d\) quark, within a leading-…

Sensitivity of Two-Body Non-Leptonic Branching Fractions to Theoretical Mass Variations in Heavy-Light Mesons
Manakkumar Parmar, Ajay Kumar Rai
This study investigates the sensitivity of two-body non-leptonic branching fractions to theoretical mass variations in heavy-light mesons (, , , and ). Utilizing th…
