Structure of renormalization constants for theories with multiple couplings in the MS-like subtraction schemes

Nuclear Physics B
For theories with multiple couplings we construct simple expressions for the four-dimensional (or, in general, integer-dimensional) renormalization constants assuming that all divergences are logarithmical.

Neutralino dark matter in the extension of MSSM with two triplets and singlet

European Physical Journal C: Particles and Fields
In an extension of MSSM with two triplets and a singlet, called the TNMSSM, there are seven neutralinos which can enrich the study of cold dark matter if one expects that the weakly interacting massive particle (WIMP) is responsible for the observation ...

Is Quantum Field Theory Necessarily “Quantum”?

Quantum Reports
The mathematical universe of the quantum topos, which is formulated on the basis of classical Boolean snapshots, delivers a neo-realist description of quantum mechanics that preserves realism.

Renormalization in open quantum field theory. Part I. Scalar field theory

Journal of High Energy Physics, 2017
While the notion of open quantum systems is itself old, most of the existing studies deal with quantum mechanical systems rather than quantum field theories.

Meso-inflationary Peccei–Quinn Symmetry Breaking with Nonminimal Coupling

The Astrophysical Journal Supplement Series
We study a realization of the inflationary scenario where the Peccei–Quinn (PQ) symmetry is spontaneously broken during inflation, facilitated by its nonminimal coupling to gravity.

A Gentle Introduction to Lattice Field Theory

Entropy
The principles of Lattice Field Theory (LFT), in particular Lattice Gauge Theory (LGT), are explained for a nonspecialist audience. We describe some of the successes of the program; we also discuss the relationship between LFT and Quantum Cellular ...

Galaxy Clusters in Dark Matter Window: The Case of the Shapley Supercluster

Universe
Dark matter dominates the matter content of the Universe, yet its particle nature remains elusive. Among the promising multi-messenger astronomy dark matter candidates are weakly interacting massive particles and superheavy dark matter, both of which may
