Analytical determination of Yukawa Potential: An iterative semiclassical approach [PDF]
Revista Brasileira de Ensino de Física, 2020 In this work we propose an alternative semiclassical iterative approach to obtain the Yukawa Potential, where the temporal evolution is replaced by the number of iterations.

Heavy-quark mesons in the diabatic approach: string breaking and the quarkoniumlike spectrum [PDF]
EPJ Web of Conferences, 2022 The Born-Oppenheimer approximation provides a description of heavy-quark mesons firmly based on lattice QCD, but its validity is limited to the lightest states lying far below the first open-flavour meson-meson threshold.

Physics Letters B, 2021 A novel observable measuring the CP asymmetry in multi-body decays of heavy mesons, which is called the forward-backward asymmetry induced CP asymmetry (FBI-CPA), ACPFB, is introduced. This observable has the dual advantages that 1) it can isolate the CP

The Ds0(2590)+ as the dressed cs¯(21S0) meson in a coupled-channels calculation
Physics Letters B, 2022 The recent discovery of the Ds0(2590)+ meson by the LHCb Collaboration has stimulated the analysis of meson-meson channels effects in the two-body quark-antiquark meson spectrum.

Menopausal Health Status of the Nepalese Women
Journal of Nepal Medical Association, 2017 Introduction: Menopause is an unavoidable and sometimes problematic condition in which women may suffer from a number of health problems. Knowledge of the major symptoms associated with menopause helps reduce the burden and stress associated with the ...

Strong Effective Coupling, Meson Ground States, and Glueball within Analytic Confinement
Particles, 2019 The phenomena of strong running coupling and hadron mass generating have been studied in the framework of a QCD-inspired relativistic model of quark-gluon interaction with infrared-confined propagators.

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.

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
