General structure of fermion two-point function and its spectral representation in a hot magnetized medium / Das, Aritra ; Bandyopadhyay, Aritra ; Roy, Pradip K. ; Mustafa, Munshi G.
We have systematically constructed the general structure of the fermion self-energy and the effective quark propagator in the presence of a nontrivial background such as a hot magnetized medium. [...]

Quantum hair of black holes out of equilibrium / Brustein, Ram ; Medved, A. J. M.
Classically, the black hole (BH) horizon is completely opaque, hiding any clues about the state and very existence of its interior. [...]

Toward de Sitter space from ten dimensions / Moritz, Jakob ; Retolaza, Ander ; Westphal, Alexander
Using a 10D lift of nonperturbative volume stabilization in type IIB string theory, we study the limitations for obtaining de Sitter vacua. [...]

Beyond Lovelock gravity: Higher derivative metric theories / Crisostomi, M. ; Noui, K. ; Charmousis, C. ; Langlois, D.
We consider theories describing the dynamics of a four-dimensional metric, whose Lagrangian is diffeomorphism invariant and depends at most on second derivatives of the metric. [...]

Dynamical study of Ωc0 in the chiral quark model / Yang, Gang ; Ping, Jialun
Recently, the experimental results of the LHCb Collaboration suggested the existence of five new excited states of Ωc0: Ωc(3000)0, Ωc(3050)0, Ωc(3066)0, Ωc(3090)0, and Ωc(3119)0; however, the quantum numbers of these new particles are not determined now. [...]

Approach to calculation of mass spectra and two-photon decays of cc¯ mesons in the framework of Bethe-Salpeter equation / Bhatnagar, Shashank ; Alemu, Lmenew
In this work we calculate the mass spectra of charmonium for 1P,,4P states of 0++ and 1++, for 1S,,5S states of 0+, and for 1S,,4D states of 1 along with the two-photon decay widths of the ground and first excited states of 0++ quarkonia for the process O++γγ in the framework of a QCD-motivated Bethe-Salpeter equation (BSE).

Analysis of a gauged model with a spin-12 field directly coupled to a Rarita-Schwinger spin-32 field / Adler, Stephen L.
We give a detailed analysis of an Abelianized gauge field model in which a Rarita-Schwinger spin-32 field is directly coupled to a spin-12 field. [...]
