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

Meson properties in magnetized quark matter [PDF]
, 2017 We study neutral and charged meson properties in magnetic field. Taking bosolization method in a two-flavor Nambu--Jona-Lasinio model, we derive effective meson Lagrangian density with minimal coupling to the magnetic field, by employing derivative ...

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.

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

Two Meson Scattering Amplitudes and their Resonances from Chiral Symmetry and the N/D Method [PDF]
, 1999 We study the vector and scalar meson-meson amplitudes up to \sqrt{s}\lesssim 1.4 GeV and their associated spectroscopy. The study has been done considering jointly the N/D method, Chiral Symmetry and implications from large N_c QCD.

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 ...

Superconformal baryon-meson symmetry and light-front holographic QCD [PDF]
, 2015 We construct an effective QCD light-front Hamiltonian for both mesons and baryons in the chiral limit based on the generalized supercharges of a superconformal graded algebra.

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 ...

Applied Vegetation Science, Volume 25, Issue 4, October/December 2022., 2022 We demonstrated a new workflow to extend and map a national classification into a new area. Three associations could be mapped using remotely sensed predictors alone (Sentinel and LiDAR), whereas two also required environmental predictors. Our map will guide the indigenous peoples of the area to manage threats to valued communities and their species ...
