Relics of Supersymmetry in Ordinary 1-flavor QCD: Hairpin Diagrams and Scalar-Pseudoscalar Degeneracy [PDF]

open access: yes, 2007
The large-$N_c$ orientifold planar equivalence between $\mathcal{N}=1$ SUSY Yang-Mills theory and ordinary 1-flavor QCD suggests that low-energy quark-gluon dynamics in QCD should be constrained by the supersymmetry of the parent theory.

Strong decays of vector mesons to pseudoscalar mesons in the relativistic quark model

open access: yesPhysics Letters B, 2015
Strong decays of vector (S13) mesons to the pair of pseudoscalar (S01) mesons are considered in the framework of the microscopic decay mechanism and the relativistic quark model based on the quasipotential approach.

The $$\pi f_0(500)$$ π f 0 ( 500 ) decay of the $$a_1(1260)$$ a 1 ( 1260 )

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We evaluate the $$a_1(1260) \rightarrow \pi \sigma (f_0(500))$$ a 1 ( 1260 ) → π σ ( f 0 ( 500 ) ) decay width from the perspective that the $$a_1(1260)$$ a 1 ( 1260 ) resonance is dynamically generated from the pseudoscalar–vector interaction and the $$\

Chiral extrapolation of lattice data for the hyperfine splittings of heavy mesons [PDF]

open access: yes, 2001
Hyperfine splittings between the heavy vector (D*, B*) and pseudoscalar (D, B) mesons have been calculated numerically in lattice QCD, where the pion mass (which is related to the light quark mass) is much larger than its physical value.

Composition of the pseudoscalar η and η′ mesons [PDF]

open access: yesJournal of High Energy Physics, 2007
The composition of the eta and eta' mesons has long been a source of discussion and is of current interest with new experimental results appearing. We investigate what can be learnt from a number of different processes: V to P gamma and P to V gamma (V and P are light vector and pseudoscalar mesons respectively), P to gamma gamma, J/psi,psi' to P gamma,

Direct CP Violation from Isospin Symmetry Breaking Effects for the Decay Process B-s→P(V)π0 in PQCD

open access: yesAdvances in High Energy Physics, 2019
We investigate the direct CP violation for the decay process of B-s→P(V)π0 (P,V refer to the pseudoscalar meson and vector meson, resp.) via isospin symmetry breaking effects from the π0-η-η′ mixing mechanism in PQCD factorization approach.

Effective Lagrangian approach to vector mesons, their structure and decays$^{*)}$

open access: yes, 1996
An improved update of the structure and decays of $\rho^0$, $\omega$ and $\phi$ mesons based on a chiral SU(3) Lagrangian, including anomaly terms is presented.

Weak decays of $$B_c$$ Bc into two hadrons under flavor SU(3) symmetry

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
A large number of $$B_c$$ Bc meson events have been recorded at the LHCb detector, especially some two-body hadronic decay modes. We analyzed the weak decays of the $$B_c$$ Bc meson into two hadron states under the flavor SU(3) symmetry.
