Probing the Rare Four-Bottom Higgs Decay at the HL-LHC and ILC

Alexander Belyaev, Eduard Boos, Vyacheslav Bunichev +2

We propose the rare SM Higgs decay as a probe of the structure of Higgs interactions with bottom quarks and gauge bosons, and as a baseline for searches for…

Photon spheres near black holes in a model with anisotropic fluid

V. D. Ivashchuk, S. V. Bolokhov, F. B. Belissarova +4

The semi-review paper studies the null geodesics which appear for black hole solutions in the gravitational model with anisotropic fluid. The equations of state for the fluid…

Stability Analysis of Circular Geodesics in Dyonic Dilatonic Black Hole Spacetimes

Kuantay Boshkayev, Gulnaz Takey, Vladimir Ivashchuk +3

This research investigates a non-extreme dyonic-like dilatonic charged black hole solution within a four-dimensional gravity model. This model incorporates two scalar (dilaton) fie…
