Scalar and Pseudoscalar Correlators in Yang-Mills Theory
Scalar Pseudoscalar Correlators Yang-Mills Theory
2010/12/27
Correlation functions of the FF and F\tilde{F} operators in hot SU(3) Yang-Mills theory have recently been studied both on the lattice and in perturbation theory, and the results subsequently compare...

2011/1/7
Correlation functions of the FF and F\tilde{F} operators in hot SU(3) Yang-Mills theory have recently been studied both on the lattice and in perturbation theory, and the results subsequently compared...
We present first results on the axial and pseudoscalar $\Delta$ form factors. The analysis is carried out in the quenched approximation where statistical errors are small and the lattice set-up can be...

Dynamical generation pseudoscalar resonances
2011/1/7
We study the interactions between the f0(980) and a0(980) scalar resonances and the lightest pseudoscalar mesons. We first obtain the elementary interaction amplitudes, or interacting kernels, without...

We present first results on the axial and pseudoscalar D form factors. The analysis is carried
out in the quenched approximation where statistical errors are small and the lattice set-up can be inves...

2010/5/7
The data collected by the KLOE Collaboration at the Frascati φ-factory DAΦNE from 2001 to 2006 have been used for extensive studies in meson spectroscopy. The decays of the scalar mesons a0(980) and f...
Atomic Ionization by keV-scale Pseudoscalar Dark Matter Particles
Atomic Ionization keV-scale Pseudoscalar Dark Matter Particles
2010/3/16
Using the relativistic Hartree-Fock approximation, we calculate the rates of atomic ionization by absorption of pseudoscalar particles in the mass range from 10 to $\sim$ 50 keV. We present numerical ...
We review the physics of purely leptonic decays of $\pi^\pm$, $K^\pm$, $D^{\pm}$, $D_s^\pm$, and $B^\pm$ pseudoscalar mesons. The measured decay rates are related to the product of the relevant weak-i...

The Electromagnetic Properties the Light Pseudoscalar Mesons the Primakoff Effect
2010/10/25
The PrimEx (Primakoff Experiment) Collaboration is currently preparing to perform a high precision (1.4%) measurement of the two photon decay width of the neutral pion, ¡¼o!°°. The propos...
Topological Charge Screening and Pseudoscalar Glueballs
Topological Charge Screening Pseudoscalar Glueballs
2010/10/25
Topological charge screening in the QCD vacuum is found to provide crucial nonperturbative contributions to the short-distance expansion of the pseudoscalar (0¡+) glueball correlator. The screen...
Weak Decay Constant of Pseudoscalar Mesons in a QCD-Inspired Model
Weak Decay Constant Pseudoscalar Mesons a QCD-Inspired Model
2010/10/19
We show that a linear scaling between the weak decay constants of pseudoscalars and the vector meson masses is supported by the available experimental data. The decay constants scale as fm=f¼ =...
