Quintic Modification to Lifshitz Quasi-topological Black Holes
A. Bazrafshan, A. R. Olamaei, M. Ghanaatian
We extend the analysis of Lifshitz black holes to quintic order in five-dimensional quasi-topological gravity coupled to a massive Abelian vector field. Starting from a static ansa…
Comprehensive Mass Predictions: From Triply Heavy Baryons to Pentaquarks
S. Rostami, A. R. Olamaei, M. Malekhosseini +1
In this article, we use two different methods for studying the mass spectra of fully-heavy baryons and pentaquarks. In the first section, we use state-of-the-art machine learning m…
The allowed baryon to baryon-meson strong transitions
A. R. Olamaei, S. Rostami, K. Azizi
We investigate the kinematically allowed baryon to baryon-meson strong transitions in all the light and heavy sectors. We consider only the ground state on-shell particles in the b…
Meson mass and width: Deep learning approach
M. Malekhosseini, S. Rostami, A. R. Olamaei +2
It is fascinating to predict the mass and width of the ordinary and exotic mesons solely based on their quark content and quantum numbers. Such prediction goes beyond conventional…
Reissner-Nordström Black Holes in Quintic Quasi-topological Gravity
A. R. Olamaei, A. Bazrafshan, M. Ghanaatian
This paper investigates charged black holes within the framework of quintic quasi-topological gravity, focusing on their thermodynamics, conserved quantities, and stability. We con…
Charm content of the proton: An analytic calculation
A. R. Olamaei, S. Rostami, K. Azizi
According to general understanding, the proton as one of the main ingredients of the nucleus is composed of one down and two up quarks bound together by gluons, described by Quantu…
Strong Vertices of Doubly Heavy Spin-3/2 Baryons with Light Pseudoscalar Mesons
A. R. Olamaei, K. Azizi, S. Rostami
The strong coupling constants are basic quantities that carry information of the strong interactions among the baryon and meson multiplets as well as information on the natures and…
Strong interaction of doubly heavy spin-3/2 baryons with light vector mesons
K. Azizi, A. R. Olamaei, S. Rostami
We calculate the strong coupling constants among the doubly heavy spin- baryons and , with and being or quark, with ligh…
Surface Terms of Quintic Quasitopological Gravity and Thermodynamics of Quasi-Topological Magnetic Brane Coupled to Nonlinear Electrodynamics
A. Bazrafshan, A. R. Olamaei
For the the quintic quasitopological action which has no well-defined variational principle, we introduced a surface term that for a spacetime with flat boundaries make the action…
Strong Coupling Constants of the Doubly Heavy Baryons with Meson
A. R. Olamaei, K. Azizi, S. Rostami
The doubly charmed state is the only listed baryon in PDG, which was discovered in the experiment. The LHCb collaboration gets closer to discovering the second…
Thermodynamics of static solutions in (n+1)-dimensional Quintic Quasitopological gravity
A. Bazrafshan, F. Naeimipour, A. R. Olamaei +1
Based on the fact that some important theories like string and M-theories predict spacetime with higher dimensions, so, in this paper, we aim to construct a theory of quintic quasi…
Stability Catalyzer for a Relativistic Non-Topological Soliton Solution
Mohammad Mohammadi
For a real nonlinear Klein-Gordon Lagrangian density with a special solitary wave solution (SSWS), which is essentially unstable, it is shown how adding a proper additional massles…
Non-Topological Solitons in Dimensions
M. Mohammadi, A. R. Olamaei
The paper, classically, presents a special stable non-topological solitary wave packet solution in dimensions for an extended complex non-linear Klein-Gordon (CNKG) field sys…
Rare Radiative Decays of Vector and Axial-Vector Mesons to Final States

In this work, we use the QCD sum rule method to study the radiative decays of the vector and axial-vector mesons to each of three charmed strange mesons, , and $…
Beautiful mathematics for beauty-full and other multi-heavy hadronic systems
K. Azizi, A. R. Olamaei, S. Rostami
In most non-perturbative methods in hadron physics the calculations are started with a correlation function in terms of some interpolating and transition currents in -space. F…
Rare Radiative Transition in QCD
K. Azizi, N. Ghahramani, A. R. Olamaei
We investigate the radiative transition in the framework of QCD sum rules. In particular, we calculate the transition form factors responsible for this decay i…
