Analysis of the b 1 meson decay in local tensor bilinear representation

open access: yesJournal 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

Dilepton Spectra from Decays of Light Unflavored Mesons [PDF]

open access: yes, 1999
The invariant mass spectrum of the $e^{+}e^{-}$ and $\mu ^{+}\mu ^{-}$ pairs from decays of light unflavored mesons with masses below the $\phi (1020)$-meson mass to final states containing along with a dilepton pair one photon, one meson, and two mesons

Towards the Assignment for the Ground Scalar Meson

open access: yesAdvances 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

Measurement of branching fractions for D meson decaying into ϕ meson and a pseudoscalar meson

open access: yesPhysics Letters B, 2019
The four decay modes $D^{0}\to ^{0}$, $D^{0}\to $, $D^{+}\to ^{+}$, and $D^{+}\to K^{+}$ are studied by using a data sample taken at the centre-of-mass energy $\sqrt{s} = 3.773$~GeV~with the BESIII detector, corresponding to an integrated luminosity of 2.93 fb$^{-1}$. The branching fractions of the first three decay modes are measured to be ${

Cross sections for 2-to-1 meson–meson scattering

open access: yesEuropean 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 ...

Medium induced Lorentz symmetry breaking effects in nonlocal PNJL models [PDF]

open access: yes, 2014
In this paper we detail the thermodynamics of two flavor nonlocal Polyakov-Nambu-Jona-Lasinio models for different parametrizations of the quark interaction regulators.

Concavity of the meson Regge trajectories

open access: yesPhysics Letters B, 2018
It is illustrated by the fitted Regge trajectories for a large majority of mesons that the radial and orbital Regge trajectories for mesons prefer being concave in the (nr,M2) and (l,M2) planes, respectively. The concavity of the meson Regge trajectories

The role of meson exchanges in light-by-light scattering

open access: yesPhysics Letters B, 2017
We discuss the role of meson exchange mechanisms in γγ→γγ scattering. Several pseudoscalar (π0, η, η′(958), ηc(1S), ηc(2S)), scalar (f0(500), f0(980), a0(980), f0(1370), χc0(1P)) and tensor (f2(1270), a2(1320), f2′(1525), f2(1565), a2(1700)) mesons are ...

PELANGGARAN CP UNTUK BAURAN PARTIKEL Bs;d DENGAN MENGGUNAKAN KERANGKA KERJA TEORI PELANGGARAN FLAVOR MINIMAL

open access: yesJurnal 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.
