Predictions for the scalar partner of the LHC tetraquark
Muhammad Naeem Anwar, Timothy J. Burns
We consider how the recent CMS measurements of the masses and quantum numbers of , and can help to reveal the internal structure of these apparent $cc\…
Long-range interactions in double heavy tetraquarks
Muhammad Naeem Anwar
At the large distances compared to the chiral symmetry breaking scale, a four-quark system (with as heavy and as light quarks) can be treated as two asym…
Heavy quark spin partners of the in coupled-channel formalism
Muhammad Naeem Anwar, Yu Lu
The charmoniumlike state is described as predominantly a molecule in a coupled-channel quark model [Phys.\,Rev.\,D\,\textbf{96},\,114022\,(2017)]. The heavy…
Quark structure of the and resonances and their strong and radiative decays
J. Ferretti, E. Santopinto, M. Naeem Anwar +1
We calculate the masses of states with threshold corrections in a coupled-channel model. The model was recently applied to the description of the properties of $χ_{…
The baryo-quarkonium picture for hidden-charm and bottom pentaquarks and LHCb and states
J. Ferretti, E. Santopinto, M. N. Anwar +1
We study baryo-charmonium [- and -, -, - and -] and baryo-bottomonium [-, - and -$…
Spectroscopy of the hidden-charm and tetraquarks
Muhammad Naeem Anwar, Jacopo Ferretti, Elena Santopinto
We calculate the spectrum of and tetraquarks, where , and stand for light (), strange and charm quarks, respectively, in a rel…
Multiplet Revisited: Ultrafine Mass Splitting and Radiative Transitions
Muhammad Naeem Anwar, Yu Lu, Bing-Song Zou
Invoked by the recent CMS observation regarding candidates of the multiplet, we analyze the ultrafine and mass splittings among multiplet in our unquenched quark mod…
Heavy Quark Spin Symmetry Violating Hadronic Transitions of Higher Charmonia
Muhammad Naeem Anwar, Yu Lu, Bing-Song Zou
In heavy quarkonia, hadronic transitions serve as an enlightened probe for the structure and help to establish the understanding of light quark coupling with a heavy degree of free…
Spectroscopy and decays of the fully-heavy tetraquarks
Muhammad Naeem Anwar, Jacopo Ferretti, Feng-Kun Guo +2
We discuss the possible existence of the fully-heavy tetraquarks. We calculate the ground-state energy of the bound state, where stands for the bottom quark,…
Revisited: A Coupled Channel Perspective
Yu Lu, Muhammad Naeem Anwar, Bing-Song Zou
We calculate the probabilities of various charmed meson molecules for under the framework of model. The results indicate that even though heavy quark spin symme…
How Large is the Contribution of Excited Mesons in Coupled-Channel Effects?
Yu Lu, Muhammad Naeem Anwar, Bing-Song Zou
We study the excited mesons' contributions to the coupled-channel effects under the framework of model for the bottomonium. Contrary to what has been widely accepted,…
Modeling Charmonium- Decays of Higher Charmonia
Muhammad Naeem Anwar, Yu Lu, Bing-Song Zou
We propose a new model to create a light meson in the heavy quarkonium transition, which is inspired by the NambuJona-Lasinio (NJL) model. Hadronic transitions of $J^{PC}=1^{--}…
Coupled-Channel Effects for the Bottomonium with Realistic Wave Functions
Yu Lu, Muhammad Naeem Anwar, Bing-Song Zou
With Gaussian expansion method (GEM), realistic wave functions are used to calculate coupled-channel effects for the bottomonium under the framework of model. The simplic…
