Phenomenology of Hypothetical Single-Top Hadronic States

Z. Rajabi Najjar, M. Ahmadi, K. Azizi

The paper uses QCD sum‑rule techniques to predict the masses of hypothetical baryons and mesons that contain a single top quark, assessing whether such states could be weakly bound…

Masses of Purely Top-Quark Bound States: Toponium and the Triply-Top Baryon

Z. Rajabi Najjar, K. Azizi

We investigate the pseudoscalar ( $I^\cdot_{t}$ ) and vector ( $I ¨ _{t}$ ) toponium states, as well as the triply-top baryon ( $I^c ◯_{ttt}$ ), using the QCD sum-rule method. This study was motivated…

Study of the semileptonic decay $I^ \to p ℓ I^ˉ ½_{ℓ}$ in QCD

M. Ahmadi, Z. Rajabi Najjar, K. Azizi

We conduct a comprehensive study of the semileptonic decay process $Î\to p\,\ell\,\barÎ½_{\ell}$, focusing on the determination of all six vector and axial-vector form factors t…

Semileptonic decay of the triply heavy $I^c ◯_{cc b}$ to the observed $I^_{cc}^{++}$ state

Z. Rajabi Najjar, K. Azizi, H. R. Moshfegh

We investigate the weak semileptonic decay of the $I^c ◯_{cc b}^{+} \to I^_{cc}^{++} ℓ I^ˉ ½_{ℓ}$ , where a triply heavy baryon with spin 1/2 decays into the observed…
