Abstract We study the axion and axion-like particle production from the η → ππa decay within the SU(3) chiral perturbation theory up to the one-loop level. The conventional SU(3) chiral low energy constants are found to be able to reabsorb all t

Abstract We study the mixing of the QCD/QCD-like axion and light-flavor mesons π 0, η, η′ within the framework of U(3) chiral perturbation theory up to next-to-leading order in this work. The axion-meson mixing formulas are calculated order by o

Abstract In this work, we perform a detailed study of the τ − → π − π 0 γν decay process within the resonance chiral theory. We pay special attention to the triple-product asymmetry in the τ − → π − π 0 γν process. The minimal r

Abstract In this work, we determine up/down-quark mass $$m_{q=u/d}$$ m q = u / d in the isoscalar scalar channel from both the Shifman–Vainshtein–Zakharov (SVZ) and the Monte-Carlo-based QCD sum rules. The relevant spectral function, including th

We study the newly reported hidden-charm pentaquark candidates Pc(4312), Pc(4440) and Pc(4457) from the LHCb Collaboration, in the framework of the effective-range expansion and resonance compositeness relations. The scattering lengths and effective

Abstract We study the scattering of the light-flavor pseudoscalar mesons ($$\pi , K, \eta $$ π,K,η ) off the ground-state charmed mesons ($$D,D_s$$ D,Ds ) within chiral effective field theory. The recent lattice simulation results on various scatte

In this work, we study the resonances near the thresholds of the open heavy-flavor hadrons using the effective-range-expansion method. The unitarity, analyticity, and compositeness coefficient are also taken into account in our theoretical formalism.

Start codon targeted polymorphism (SCoT) analysis was employed to distinguish 37 whipgrass (Hemarthria compressa L.) clones and assess the genetic diversity and population structure among these genotypes. The informativeness of markers was also estim

We compute the scalar and pseudoscalar spectral functions by using their form factors calculated within the unitarized U(3) chiral perturbation theory (χPT). The extrapolation to larger values of NC and the spectral function sum rules are discussed
