PSEUDOSCALAR MESON ELECTROPRODUCTION AND TRANSVERSITY [PDF]

open access: yesExclusive 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.

The Isgur-Wise function: A lattice determination from pseudoscalar → pseudoscalar form factors [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 1994
Form factors for pseudoscalar --> pseudoscalar decays of heavy-light mesons are found in quenched lattice QCD with heavy-quark masses in the range of approximately 1-2 GeV. The Isgur-Wise function, $ ( )$, is extracted from these form factors. Results are in good agreement with $ ( )$ derived from CLEO measurements for B --> D*.

Spin-axion coupling [PDF]

open access: yes, 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 ...

Chiral Properties of Pseudoscalar Mesons on a Quenched $20^4$ Lattice with Overlap Fermions [PDF]

open access: yes, 2001
The chiral properties of the pseudoscalar mesons are studied numerically on a quenched $20^4$ lattice with the overlap fermion. We elucidate the role of the zero modes in the meson propagators, particularly that of the pseudoscalar meson.

Discovering the Higgs with Low Mass Muon Pairs [PDF]

open access: yes, 2009
Many models of electroweak symmetry breaking have an additional light pseudoscalar. If the Higgs boson can decay to a new pseudoscalar, LEP searches for the Higgs can be significantly altered and the Higgs can be as light as 86 GeV. Discovering the Higgs

Strange and Charm Quark Spins from Anomalous Ward Identity [PDF]

open access: yes, 2017
We present a calculation of the strange and charm quark contributions to the nucleon spin from the anomalous Ward identity (AWI). It is performed with overlap valence quarks on 2+1-flavor domain-wall fermion gauge configurations on a $24^3 \times 64 ...
