A Brunn-Minkowski Inequality for Symplectic Capacities of Convex Domains

Shiri Artstein-Avidan, Yaron Ostrover

In this work we prove a Brunn-Minkowski-type inequality in the context of symplectic geometry and discuss some of its applications.

Study of GEM-like detectors with resistive electrodes for RICH applications

A. G. Agocs, A. Di Mauro, A. Ben David +4

We have developed prototypes of GEM-like detectors with resistive electrodes to be used as RICH photodetectors equipped with CsI photocathodes. The main advantages of these detecto…

On optimality of Bayesian testimation in the normal means problem

Felix Abramovich, Vadim Grinshtein, Marianna Pensky

We consider a problem of recovering a high-dimensional vector observed in white noise, where the unknown vector is assumed to be sparse. The objective of the paper is to de…

Baby Skyrmions on the Two-Sphere

Itay Hen, Marek Karliner

We find the static multi-soliton solutions of the baby Skyrme model on the two-sphere for topological charges 1 =< B =< 14. Numerical full-field results show that the charge-one Sk…

Gluon Scattering in Deformed N=4 SYM

Yaron Oz, Stefan Theisen, Shimon Yankielowicz

We consider gluon and gluino scattering amplitudes in large N beta-deformed N=4 SYM with real beta. A direct inspection of the planar diagrams shows that the scattering amplitudes…

Effective field theories for QCD with rooted staggered fermions

Claude Bernard, Maarten Golterman, Yigal Shamir

Even highly improved variants of lattice QCD with staggered fermions show significant violations of taste symmetry at currently accessible lattice spacings. In addition, the "rooti…
