Hadronic Molecule Interpretation of Tcc+ and Its Beauty Partners
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 Motivated by the latest discovery of a new tetraquark Tcc+ with two charm quarks and two light antiquarks by LHCb Collaboration, we investigated the DD∗ hadronic molecule interpretation of Tcc+. By calculation, the mass and the decay width of this new structure Tcc+ can be understood in one‐meson exchange potential model. The binding energies for these

On the Interpretation of Nonresonant Phenomena at Colliders
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 With null results in resonance searches at the LHC, the physics potential focus is now shifting towards the interpretation of nonresonant phenomena. An example of such shift is the increased popularity of the EFT programme. We can embark on such programme owing to the good integrated luminosity and an excellent understanding of the detectors, which ...

SU(3) analysis of fully-light tetraquarks in heavy meson weak decays
European Physical Journal C: Particles and Fields, 2021 We perform a SU(3) analysis for both semi-leptonic and non-leptonic heavy meson weak decays into a pseudoscalar meson and a fully-light tetraquark in 10 or 27 representation.

Calculation of Binding Energy and Wave Function for Exotic Hidden‐Charm Pentaquark
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 In this study, pentaquark Pc(4380) composed of a baryon Σc, and a D¯∗ meson is considered. Pentaquark is as a bound state of two‐body systems composed of a baryon and a meson. The calculated potential will be expanded and replaced in the Schrödinger equation until tenth sentences of expansion.

Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 We investigate the exclusive semileptonic and rare D⟶π(K) decays within the standard model together with the light‐front quark model (LFQM) constrained by the variational principle for the QCD‐motivated effective Hamiltonian. The form factors are obtained in the q+ = 0 frame and then analytically continue to the physical timelike region.

Assignments of the X(4140), X(4500), X(4630), and X(4685) Based on the QCD Sum Rules
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 In this article, we take into account our previous calculations based on the QCD sum rules, and tentatively assign the X(4630) as the Ds∗D¯s1−Ds1D¯s∗ tetraquark molecular state or csPc¯s¯A+csAc¯s¯P tetraquark state with the JPC = 1−+, and assign the X(3915) and X(4500) as the 1S and 2S csAc¯s¯A tetraquark states, respectively, with the JPC = 0++. Then,

Study of the Ground‐State Energies of Some Nuclei Using Hybrid Model
Advances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021 The quark‐quark (QQ) interaction as a perturbed term to the nucleon‐nucleon interaction (NN) without any coupling between them is studied in a hybrid model. This model is used to calculate the ground‐state energies of 2H1 and 4He2 nuclei. In a semirelativistic framework, this model is encouraged for light nuclei and the instanton‐induced interaction by

Trace and Axial Anomalies on Equal Footing
Advances in High Energy Physics, 2020 We discussed that for some particular nonsupersymmetric theories, a generalized symmetry that includes both the scale and axial transformations and leads to a single current may contain also a pseudoscalar term. The method, inspired by the superconformal
