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

Charmed scalar resonances -- Conventional and four-quark mesons [PDF]
Prog.Theor.Phys. 114 (2005) 205-211, 2005 We propose that there coexist two scalar mesons of different structures (a conventional meson and a four-quark meson) in the recently observed broad bumps just below the large peak of the tensor meson in the D-pi mass distribution. We base this proposal on the interpretation of the charm-strange scalar meson of mass 2317 MeV as a four-quark meson.

Mesons in Nuclei: η and ω Mesons [PDF]
Progress of Theoretical Physics Supplement, 2010 Data on the photoproduction of omega mesons on nuclei have been re-analyzed in search for in-medium modifications. The data were taken with the Crystal Barrel(CB)/TAPS detector system at the ELSA accelerator facility in Bonn. The extracted omega line shape was found to be sensitive to the background subtraction.

Meson-Meson Interactions and Resonances in the 't Hooft Model [PDF]
Phys.Rev. C69 (2004) 035209, 2003 We studied meson-meson interactions using the 't Hooft model, which represents QCD in 1+1 dimensions and assumes a large number of colors ($N_c$). The dominant interactions in this large $N_c$ limit are generated by quark exchange. Our results show that QCD in 1+1 dimensions allows the realization of a constituent-type quark model for the mesons, and ...

Distortion of the HBT images by meson clouds [PDF]
Prog.Theor.Phys.122:1301-1310,2010, 2009 We study the effects of mesonic final state interactions on the Hanbury Brown and Twiss (HBT) intensity interferometry for mesons in ultra-relativistic heavy ion collisions. Modification of the one-body amplitude of emitted mesons while going through a cloud of other mesons is estimated in the semiclassical approximation with a mesonic optical ...

Jurnal Neutrino: Jurnal Fisika dan Aplikasinya, 2014 Meson merupakan partikel yang disusun oleh satu quark (materi) dan satu anti-quark (anti-materi) yang terikat gaya nuklir kuat. Ada tiga partikel meson yang istimewa: meson B, meson D, dan meson K. Terpisah dari pembahasan meson D dan meson K.

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.

Enhanced production of $ψ(2S)$ mesons in heavy ion collisions [PDF]
Phys. Rev. C 91, 054914 (2015), 2014 We study the production of a $\psi(2S)$ meson in heavy ion collisions. We evaluate Wigner functions for the $\psi(2S)$ meson using both Gaussian and Coulomb wave functions, and investigate the wave function dependence in the $\psi(2S)$ meson production by recombination of charm and anti-charm quarks.
