Two photon decay width of the fully charmed tetraquarks: revisiting prospects for ultraperipheral collisions
We discuss the role of fully heavy tetraquarks in ultraperipheral collisions AA AA\, J/ψJ/ψ and AA AA\, γγ. Two-photon couplings to scalar and tensor tetraquarks are considered. We use…

Spontaneous CP violation in the D5-symmetric four-Higgs-doublet models
We constructed a four-Higgs-doublet model (4HDM) invariant under D5 symmetry and investigated its complete neutral vacuum structure in detail. Assuming explicit CP conservation in the scalar…

Relative transverse activity as a probe of collectivity-like long-range correlations in pp collisions at s=13 TeV
Understanding the origin of collectivity-like signatures in small collision systems is a central open question in high-energy nuclear physics, and two-particle correlation functions offer unique…

The absence of global anomalies of CP symmetry
Some solutions to the strong CP problem assume that CP symmetry is a gauge symmetry, which is then spontaneously broken. For this scenario to be possible, the CP symmetry should not have any…
