Vacuum pseudoscalar susceptibility [PDF]
Physical Review C, 2010 We derive a novel model-independent result for the pion susceptibility in QCD via the isovector-pseudoscalar vacuum polarisation. In the neighbourhood of the chiral-limit, the pion susceptibility can be expressed as a sum of two independent terms. The first expresses the pion-pole contribution.

Pseudoscalar mass effects in the decays of τ with three pseudoscalar mesons [PDF]
Physical Review D, 1994 We study the effects of non-vanishing pseudoscalar masses in $ $ decays into three mesons. The hadronic matrix elements are obtained by using the generalized structure of the chiral currents with nonvanishing pseudoscalar masses and implementing the low-lying resonances in the different channels.

Vectorlike leptons and long-lived bosons at the LHC
Journal of High Energy Physics, 2023 We study a renormalizable theory that includes a heavy weak-singlet vectorlike lepton, τ ′ , that decays into a pseudoscalar boson and a tau lepton. We show that this can be the dominant decay mode of τ ′ provided the pseudoscalar couplings deviate from ...

Physics Letters B, 2022 We carry out the first lattice QCD derivation of the mixing energy and the mixing angle of the pseudoscalar charmonium and glueball on two gauge ensembles with Nf=2 degenerate dynamical charm quarks. The mixing energy is determined to be 49(6) MeV on the

Production of a Higgs pseudoscalar plus two jets in hadronic collisions [PDF]
, 1998 We consider the production of a Higgs pseudoscalar accompanied by two jets in hadronic collisions. We work in the limit that the top quark is much heavier than the Higgs pseudoscalar and use an effective Lagrangian for the interactions of gluons with the

Pseudoscalar-photon Interactions, Axions, Non-Minimal Extensions, and Their Empirical Constraints from Observations [PDF]
, 2011 Pseudoscalar-photon interactions were proposed in the study of the relations among equivalence principles. The interaction of pseudoscalar axion with gluons was proposed as a way to solve the strong CP problem.

PSEUDOSCALAR MESON ELECTROPRODUCTION AND TRANSVERSITY [PDF]
Exclusive Reactions at High Momentum Transfer IV, 2011 Exclusive meson leptoproduction from nucleons in the deeply virtual exchanged boson limit can be described by generalized parton distributions (GPDs). Including spin dependence in the description requires 8 independent quark-parton and gluon-parton functions.

, 2015 We establish a new covariant phenomenological model, which describes an influence of pseudoscalar (axion) field on spins of test massive particles. The model includes general relativistic equations of particle motion and spin evolution in background ...
