QCD-constrained dynamical spin effects in the pion holographic light-front wavefunction

Mohammad Ahmady, Farrukh Chishtie, Ruben Sandapen

Using light-front holography, we predict simultaneously the pion decay constant and the pion charge radius by taking into account (higher twist) dynamical spin effects whose relati…

Convection and Overshoot in models of gamma Doradus and delta Scuti stars

C. C. Lovekin, J. A. Guzik

We investigate the pulsation properties of stellar models representative of $δ$ Scuti and $γ$ Doradus variables. We have calculated a grid of stellar models from 1.2 to 2.2 M$_{\od…

The pion in holographic light-front QCD

M. Ahmady, F. Chishtie, R. Sandapen

We report that the pion radius, decay constant, EM and transition form factors can simultaneously and accurately be predicted in light-front holographic QCD with a universal AdS/QC…

Measurement of the decay $η^{'} \to π^{0} π^{0} η$ at MAMI

P. Adlarson, F. Afzal, C. S. Akondi +75

An experimental study of the $η^{'} \to π^{0} π^{0} η \to 6 γ$ decay has been conducted with the best up-to-date statistical accuracy, by measuring $η^{'}$ mesons produced in the $γ p \to η^{'} p$ re…

The modified trace distance of coherence is constant on most pure states

Nathaniel Johnston, Chi-Kwong Li, Sarah Plosker

Recently, the much-used trace distance of coherence was shown to not be a proper measure of coherence, so a modification of it was proposed. We derive an explicit formula for this…

The Inverse Eigenvalue Problem for Entanglement Witnesses

Nathaniel Johnston, Everett Patterson

We consider the inverse eigenvalue problem for entanglement witnesses, which asks for a characterization of their possible spectra (or equivalently, of the possible spectra resulti…

First measurement of the polarization observable $E$ and helicity-dependent cross sections in single $π^{0}$ photoproduction from quasi-free nucleons

M. Dieterle, L. Witthauer, F. Cividini +84

The double-polarization observable $E$ and the helicity-dependent cross sections $σ_{1/2}$ and $σ_{3/2}$ have been measured for the first time for single $π^{0}$ photoproduction fr…

Dynamical spin effects in the pion

M. Ahmady, F. Chishtie, R. Sandapen

We take into account dynamical spin effects in the holographic light-front pion wavefunction in order to predict the pion radius, decay constant, the pion electromagnetic and photo…

Helicity-dependent cross sections and double-polarization observable E in eta photoproduction from quasi-free protons and neutrons

L. Witthauer, M. Dieterle, S. Abt +84

Precise helicity-dependent cross sections and the double-polarization observable $E$ were measured for $η$ photoproduction from quasi-free protons and neutrons bound in the deutero…

Predictions for Diffractive $ϕ$ Meson Production Using an AdS/QCD Light-front Wavefunction

Mohammad Ahmady, Ruben Sandapen, Neetika Sharma

We compute the rate for diffractive $ϕ$ electro-production using the Color Glass Condensate dipole model. The model parameters are obtained from fits to the most recent combined HE…

Study of $η$ and $η^{'}$ photoproduction at MAMI

V. L. Kashevarov, P. Ott, S. Prakhov +87

The reactions $γ p \to η p$ and $γ p \to η^{'} p$ have been measured from their thresholds up to the center-of-mass energy $W = 1.96$ GeV with the tagged-photon facilities at the Mainz Microt…

Functional distribution monads in functional-analytic contexts

Rory B. B. Lucyshyn-Wright

We give a general categorical construction that yields several monads of measures and distributions as special cases, alongside several monads of filters. The construction takes pl…
