A way to constrain a graviton mass from astronomical observations

Alexander F. Zakharov, Predrag Jovanovic, Dusko Borka +1

The paper surveys astronomical methods for placing limits on the graviton mass, including analyses of gravitational‑wave signals from LIGO and the orbital motion of stars near the…

New limits on the Pauli forbidden transitions in 12C nuclei obtained with the complete Borexino dataset

Borexino collaboration, D. Basilico, G. Bellini +70

The Pauli exclusion principle (PEP) was tested for nucleons in nuclei using the Borexino dataset from 2007 to 2021. %the complete Borexino detector data. The approach…

The nearby He-rich superluminous supernova SN 2021bnw during photospheric phases

A. Fiore, A. Kozyreva, L. Yan +40

Aim. We present and interpret the data of the nearby hydrogen-deficient but helium-rich superluminous supernova SN 2021bnw which reached a magnitude of -20.7 at maximum luminosity…

Space-time regions of high baryon density and baryon stopping in heavy-ion collisions

Yuri B. Ivanov

Four-volumes ( spatial-3-volumelifetime) are calculated within the model of three-fluid dynamics (3FD) and compared with those of the the JET AA Microscopic Transport…

A new spin on polynomial relations among kappa classes

Alexander Alexandrov, Boris Bychkov, Petr Dunin-Barkowski +2

We prove a recent conjecture of the fourth named author with P. Norbury that states a system of universal polynomial relations among the kappa classes on the moduli spaces of algeb…

Scalar-scalar-tensor interaction in DHOST theories

S. Mironov, V. Volkova

We derive the general cubic action for perturbations about a cosmological background in the quadratic subclass of degenerate higher-order scalar-tensor (DHOST) theories, focusing o…
