Stellar evolution and axion-like particles: new constraints and hints from globular clusters in the GAIA DR3 data
S. V. Troitsky
Axion-like particles (ALPs) are hypothetical pseudoscalar bosons, natural in extensions of the Standard Model. Their interactions with ordinary matter and radiation are suppressed,…
Constraining holographic technicolor
D. G. Levkov, V. A. Rubakov, S. V. Troitsky +1
We obtain a new bound on the value of Peskin-Takeuchi S parameter in a wide class of bottom-up holographic models for technicolor. Namely, we show that weakly coupled holographic d…
Unsolved problems in particle physics
Sergey Troitsky
I consider selected (most important according to my own choice) unsolved problems in particle theory, both those related to extensions of the Standard Model (neutrino oscillations,…
Physical conditions in potential sources of ultra-high-energy cosmic rays: Updated Hillas plot and radiation-loss constraints
Ksenia Ptitsyna, Sergey Troitsky
We review basic constraints on the acceleration of ultra-high-energy (UHE) cosmic rays (CRs) in astrophysical sources, namely the geometrical (Hillas) criterion and restrictions fr…
Trends in Grand Unification: unification at strong coupling and composite models
V. A. Rubakov, S. V. Troitsky
We review several problems of conventional Grand Unification and some new approaches. In particular, we discuss strongly coupled Grand Unified Theories. Standard Model may emerge a…
