How to tell the shape of a wormhole by its quasinormal modes / Konoplya, R.A.
Here we shall show how to reconstruct the shape function of a spherically symmetric traversable Lorenzian wormhole near its throat if one knows high frequency quasinormal modes of the wormhole. [...]

Vacuum polarization energy of the Shifman–Voloshin soliton / Weigel, H. ; Graham, N.
We compute the vacuum polarization energy of soliton configurations in a model with two scalar fields in one space dimension using spectral methods. [...]

The Petrov type D equation on genus >0 sections of isolated horizons / Dobkowski-Ryłko, Denis ; Kamiński, Wojciech ; Lewandowski, Jerzy ; Szereszewski, Adam
The Petrov type D equation imposed on the 2-metric tensor and the rotation scalar of a cross-section of an isolated horizon can be used to uniquely distinguish the Kerr–(anti) de Sitter spacetime in the case the topology of the cross-section is that of a sphere. [...]

Heavy gravitino from dynamical generation of right-handed neutrino mass scale, and gravitational waves / Nagai, Ryo ; Takahashi, Fuminobu ; Yokozaki, Norimi
The absence of supersymmetric particles at the weak scale is a puzzle if supersymmetry solves the gauge hierarchy problem. [...]

Constant temperature model for nuclear level density / Zelevinsky, Vladimir ; Karampagia, Sofia ; Berlaga, Alexander
We study physics related to the nuclear level density calculated either in a realistic shell model or, equivalently, with the use of the statistical moments method. [...]

Isothermal compressibility of hadronic matter formed in relativistic nuclear collisions / Mukherjee, Maitreyee ; Basu, Sumit ; Chatterjee, Arghya ; Chatterjee, Sandeep ; et al
We present the first estimates of isothermal compressibility ( kT ) of hadronic matter formed in relativistic nuclear collisions ( sNN=7.7 GeV to 2.76 TeV) using experimentally observed quantities. [...]

Search for C violation in the decay η  →  π 0 e + e − with WASA-at-COSY / Adlarson, P. ; Augustyniak, W. ; Bardan, W. ; Bashkanov, M. ; et al
We report on the search for the rare decay η→π0e+e− which is of interest to study C violation in the electromagnetic interaction which would indicate contributions from physics beyond the Standard Model, since the allowed decay via a two-photon intermediate state is strongly suppressed. [...]
