Tetraquark operators in lattice QCD and exotic flavour states in the charm sector
Journal of High Energy Physics, 2017 We present a general class of operators resembling compact tetraquarks which have a range of colour-flavour-spin structures, transform irreducibly under the symmetries of the lattice and respect other relevant symmetries.

Analysis of the b 1 meson decay in local tensor bilinear representation
Journal of High Energy Physics, 2018 We explore the validity of vector meson dominance in the radiative decay of the b 1(1235) meson. In order to explain the violation of the vector meson dominance hypothesis in this decay process, we investigate a model where the b 1 meson strongly couples

Towards the Assignment for the Ground Scalar Meson
Advances in High Energy Physics, 2013 Combining three complementary approaches, nonrelativistic constituent quark model, Regge phenomenology, and meson-meson mixing, we obtain the mass relations which relate different meson multiplets. With the help of known meson masses, these relations can

Cross sections for 2-to-1 meson–meson scattering
European Physical Journal C: Particles and Fields, 2021 We study the processes $$K{\bar{K}} \rightarrow \phi $$ K K ¯ → ϕ , $$\pi D \rightarrow D^*$$ π D → D ∗ , $$\pi {\bar{D}} \rightarrow {\bar{D}}^*$$ π D ¯ → D ¯ ∗ , and the production of $$\psi (3770)$$ ψ ( 3770 ) , $$\psi (4040)$$ ψ ( 4040 ) , $$\psi ...

Physics Letters B, 2020 ηc-nucleus bound state energies are calculated for various nuclei. Essential input for the calculations, namely the medium-modified D and D⁎ meson masses, as well as the density distributions in nuclei, are calculated within the quark-meson coupling (QMC)

Stark effect and dissociation of mesons in holographic conductor
Journal of High Energy Physics, 2023 We study the meson spectrum of the N $$ \mathcal{N} $$ = 4 supersymmetric Yang-Mills theory with N $$ \mathcal{N} $$ = 2 fundamental hypermultiplets for a finite electric field by using the D3/D7 model.

(Anti-)Stokes scattering on kinks
Journal of High Energy Physics, 2023 At leading order, there are three inelastic scattering processes beginning with a quantum kink and a fundamental meson. Meson multiplication, in which the final state is a kink and two mesons, was treated recently.

Resolving the RpA and v2 puzzle of D0 mesons in p−Pb collisions at the LHC
Physics Letters B, 2023 It has been a challenge to understand the experimental data on both the nuclear modification factor and elliptic flow of D0 mesons in p−Pb collisions at LHC energies.
