Parton splitting scales of reclustered large-radius jets in high-energy nuclear collisions
European Physical Journal C: Particles and Fields, 2022 We carry out the first theoretical investigation on yields and the hardest parton splitting of large-radius jets reclustered from small radius ( $$R=0.2$$ R = 0.2 ) anti- $$k_t$$ k t jets in Pb + Pb collisions, and confront them with the recent ATLAS ...

Leptonic and semi-leptonic B decays [PDF]
Nuclear Physics B - Proceedings Supplements, 2001 We present results for the semi-leptonic and leptonic decays of B mesons. These non-perturbative matrix elements are important for constraining the CKM matrix. Results are presented for the pseudoscalar and vector decay constants, as well as flavour breaking ratios and heavy quark symmetry relations.

Charged-lepton mixing and lepton flavor violation [PDF]
Physics Letters B, 2015 We present a model for calculating charged-lepton mixing matrices. These matrices are an essential ingredient for predicting lepton flavor-violating rates in the lepton number nonuniversal models recently proposed to explain anomalies in B-meson decays. The model is based on work on "constrained flavor breaking" by Appelquist, Bai and Piai relating the

European Physical Journal C: Particles and Fields, 2022 Jet-medium interaction involves two important effects: jet energy loss and medium response. The search for jet-induced medium excitations is one of the hot topics in jet quenching study in relativistic nuclear collisions.

The bearable compositeness of leptons [PDF]
Journal of High Energy Physics, 2018 Abstract Partial compositeness as a theory of flavor in the lepton sector is assessed. We begin presenting the first systematic analysis of neutrino mass generation in this context, and identifying the distinctive mass textures. We then update the bounds from charged lepton flavor and CP violating observables.

Lepton mixing and the charged-lepton mass ratios [PDF]
Journal of High Energy Physics, 2018 Abstract We construct a class of renormalizable models for lepton mixing that generate predictions given in terms of the charged-lepton mass ratios. We show that one of those models leads, when one takes into account the known experimental values, to almost maximal CP -breaking phases and to almost maximal neutrinoless double-beta ...

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 ...

Probing new physics in class-I B-meson decays into heavy-light final states
Journal of High Energy Physics, 2021 With updated experimental data and improved theoretical calculations, several significant deviations are being observed between the Standard Model predictions and the experimental measurements of the branching ratios of B ¯ s 0 → D s ∗ + L ...
