A Colour-Casimir Adjacency Matrix Approach to Fully-Heavy Tetraquarks
M. Monemzadeh, N. Tazimi
We present a phenomenological framework for fully-heavy tetraquark spectroscopy based on the spectral theory of weighted graphs. The four valence partons are vertices of the comple…
Rare Exclusive Top Decays t , b M and Vector-Meson Helicity
M. Ahmadi, M. Monemzadeh, N. Tazimi
We present a leading-order study of the rare exclusive decays , where denotes a pseudoscalar or vector meson. Starting from the tree-level transition $t \to bW^* \to…
Probing the Internal Structure of via Magnetic Moment: Distinguishing Color-Singlet and Compact Configurations
M. Monemzadeh, N. Tazimi
The nature of the exotic hadron remains one of the most debated questions in hadron spectroscopy. We calculate its magnetic moment within a non-relativistic quark model t…
Pentaquark Bound States and Regge Trajectories in QCD via Bethe Salpeter Formalism
M. Ghaderi, N. Tazimi, M. Monemzadeh
We present a comprehensive calculation of pentaquark masses and Regge trajectories within the framework of the Godfrey-Isgur relativized quark model. The pentaquark is treated as a…
Kapitza Dynamics as a New Stabilization Mechanism for Heavy Tetraquarks
M. Monemzadeh, N. Tazimi
We investigate a Kapitza-inspired mechanism in which rapid oscillations in the heavy-quark interaction generate an effective short-range repulsive term in the diquark--antidiquark…
Calculation of heavy meson potential coefficients by solving Lippman-Schwinger equation
P Sadeghi Alavijeh, N Tazimi, M Monemzadeh
In the present work, we study meson systems consisting of quark-antiquark. We solve lippman-Schwinger equation numerically for heavy meson systems. We attempt to find a non-relativ…
