Abstract We report on the development and extensive characterization of co-sputtered tantala–zirconia (Ta 2 O 5 -ZrO ) thin films, with goal to decrease coating Brownian noise in present future gravitational-wave detectors. tested a variety sputtering processes different energies deposition rates, we considered effect values cation ratio η = Zr/(Zr + Ta) post-deposition heat treatment temperature T optical mechanical properties films. Co-sputtered zirconia proved be an efficient way...
A study of chiral-odd generalized parton distributions (GPDs) the nucleon is presented in bag model demonstrating that this all four GPDs are non-zero contrary to other claims literature. The results for $H_T^q(x,\xi,t)$, $E_T^q(x,\xi,t)$, $\tilde{H}_T^q(x,\xi,t)$ agree with models within a typical quark accuracy. We present one few calculations where polynomiality satisfied and sum rule $\int dx\,\tilde{E}_T^q(x,\xi,t)=0$ holds. confront our predictions from large-$N_c$ limit, lattice QCD...
The energy-momentum tensor form factors are studied in $\Phi^4$ theory to one-loop order with particular focus on the $D$-term, a particle property which has attracted lot of attention recent literature. It is shown that free Klein-Gordon value $D$-term $D_{\text{free}}=-1$ reduced $D_{\text{one-loop}} =-\frac13$ even if interaction infinitesimally small. A companion work $\Phi^3$ confirms this result may indicate it independent type as long scalar renormalizable. Dispersion relations...
