B⟶P, V Form Factors with the B‐Meson Light‐Cone Sum Rules
In this review, we discuss the calculation of the B⟶P, V form factors within the framework of the light‐cone sum rules with the light‐cone distribution amplitudes of the B‐meson. A detailed introduction to the definition, scale evolution, and phenomenological models of the B‐meson distribution amplitudes is presented.

Charmless Quasi‐Two‐Body B Decays in Perturbative QCD Approach: Taking B⟶KR⟶K+K− as Examples
Three‐body B decays not only significantly broaden the study of B meson decay mechanisms but also provide information of resonant particles. Because of complicate dynamics, it is very hard for us to study the whole phase space in a specific approach. In this review, we take B⟶KR⟶K+K− decays as examples and show the application of the perturbative QCD ...

Calculated Event Rates for Axion Detection via Atomic and Nuclear Processes
The possibility of detection of 5.5 MeV and 14.4 keV solar axions by observing axion‐induced nuclear and atomic transitions is investigated. The presence of nuclear transitions between spin orbit partners can be manifested by the subsequent deexcitation via gamma ray emissions.

SU(3) analysis of fully-light tetraquarks in heavy meson weak decays
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.

Relaxing the W′ Constraint on Compact Extradimension
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
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
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 ...

The light scalar mesons as tetraquarks
We present a numerical solution of the four-quark Bethe–Salpeter equation for ground-state scalar tetraquarks with JPC=0++. We find that the four-body equation dynamically generates pseudoscalar-meson poles in the Bethe–Salpeter amplitude.

Calculation of Binding Energy and Wave Function for Exotic Hidden‐Charm Pentaquark
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.
