Probing QCD critical fluctuations from intermittency analysis in relativistic heavy-ion collisions

Physics Letters B, 2020
It is shown that intermittency, a self-similar correlation with respect to the size of the phase space volume, is sensitive to critical density fluctuations of baryon numbers in a system belonging to the three-dimensional (3D) Ising universality class ...

Interpreting hints for lepton flavor universality violation [PDF]

, 2017
We interpret the recent hints for lepton flavor universality violation in rare $B$ meson decays. Based on a model-independent effective Hamiltonian approach, we determine regions of new physics parameter space that give a good description of the ...

Axionlike Particles, Lepton-Flavor Violation, and a New Explanation of a_{μ} and a_{e}. [PDF]

Physical Review Letters, 2019
Axionlike particles (ALPs) with lepton-flavor-violating couplings can be probed in exotic muon and tau decays. The sensitivity of different experiments depends strongly on the ALP mass and its couplings to leptons and photons.

Rare top-quark decays $$t \rightarrow cg(g)$$ t → c g ( g ) in the aligned two-Higgs-doublet model

European Physical Journal C: Particles and Fields, 2022
We update the Standard Model (SM) predictions for the branching ratios of the rare top-quark decays $$t \rightarrow cg(g)$$ t → c g ( g ) , and evaluate the maximum rates that can be reached in the aligned as well as in the four conventional two-Higgs ...
