Relaxing the W′ Constraint on Compact Extradimension
Advances in High Energy Physics, Volume 2022, Issue 1, 2022., 2022 In this paper, we study the constraint on brane tension and compactification scale for models with brane fluctuations using the results from the direct search of W′ at 13 TeV LHC, with an integrated luminosity of 36.1fb−1, in the case for which branon forms the entire cold dark matter.

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

Chiral and $U(1)_A$ restoration for the scalar/pseudoscalar meson nonets [PDF]
, 2018 We analyze the restoration pattern of the members of the scalar and pseudoscalar meson nonets under chiral $O(4)$ and $U(1)_A$ symmetries. For that purpose, we exploit QCD Ward Identities (WI), which allow one to relate susceptibilities with quark ...

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.

The pseudoscalar meson electromagnetic form factor at high Q2 from full lattice QCD [PDF]
, 2017 We give an accurate determination of the vector (electromagnetic) form factor, F(Q^2), for a light pseudoscalar meson up to squared momentum transfer Q^2 values of 6 GeV^2 for the first time from full lattice QCD, including u, d, s and c quarks in the ...

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.

Constructing new pseudoscalar meson nonets with the observed $X(2100)$, $X(2500)$ and $\eta(2225)$ [PDF]
, 2017 Stimulated by the BESIII observation of $\eta(2100)$, $X(2500)$ and $\eta(2225)$, we try to pin down new pseudoscalar meson nonets with these states. The mass spectrum analysis and strong decay study indicate that $X(2120)$ and $\eta(2225)$ associated ...
