Shape isomers of light nuclei from the stability and consistency of the SU(3) symmetry / Cseh, J. ; Riczu, G. ; Darai, J.
We investigate the stability and self-consistency of the SU(3) symmetry and quadrupole deformation in light nuclei in terms of the Nilsson model and quasi-dynamical symmetry. [...]

Non-singular bouncing cosmology with positive spatial curvature and flat scalar potential / Matsui, Hiroki ; Takahashi, Fuminobu ; Terada, Takahiro
We find a class of solutions for a homogeneous and isotropic universe in which the initially expanding universe stops expanding, experiences contraction, and then expands again (the “bounce”), in the framework of Einstein gravity with a real scalar field without violating the null energy condition nor encountering any singularities. [...]

Hairy black holes, boson stars and non-minimal coupling to curvature invariants / Brihaye, Y. ; Ducobu, L.
The Einstein-Klein-Gordon Lagrangian is supplemented by a non-minimal coupling of the scalar field to specific geometric invariants: the Gauss-Bonnet term and the Chern-Simons term. [...]

Search for dark matter in events with a leptoquark and missing transverse momentum in proton-proton collisions at 13 TeV / Sirunyan, A.M. ; Tumasyan, A. ; Adam, W. ; Ambrogi, F. ; et al
A search is presented for dark matter in proton-proton collisions at a center-of-mass energy of s=13 TeV using events with at least one high transverse momentum ( pT ) muon, at least one high- pT jet, and large missing transverse momentum. [...]

Unification of flavor, CP , and modular symmetries / Baur, Alexander ; Nilles, Hans Peter ; Trautner, Andreas ; Vaudrevange, Patrick K.S.
Flavor symmetry plays a crucial role in the standard model of particle physics but its origin is still unknown. [...]

Superconformal vector multiplet self-couplings and generalised Fayet-Iliopoulos terms / Kuzenko, Sergei M.
As an extension of the recent construction of generalised Fayet-Iliopoulos terms in N=1 supergravity given in [1] , we present self-interactions for a vector multiplet coupled to conformal supergravity. [...]

Tidal effects away from the equatorial plane in Kerr backgrounds / Banerjee, Pritam ; Paul, Suvankar ; Shaikh, Rajibul ; Sarkar, Tapobrata
Tidal effects on self-gravitating Newtonian stars rotating around a Kerr black hole in stable spherical orbits away from the equatorial plane are exemplified by a non-vanishing Carter's constant, and are substantially different from those on the equatorial plane. [...]
