The electro-weak couplings of the top and bottom quarks — Global fit and future prospects [PDF]
Journal of High Energy Physics, 2019 We evaluate the implications of LHC and LEP/SLC measurements for the electro-weak couplings of the top and bottom quarks. We derive global bounds on the Wilson coefficients of ten two-fermion operators in an effective field theory description.

From D s → γ in lattice QCD to B s → μμγ at high q 2
Journal of High Energy Physics, 2023 We use a recent lattice determination of the vector and axial D s → γ form factors at high squared momentum transfer q 2 to infer their B s → γ counterparts. To this end, we introduce a phenomenological approach summarized as follows.

Associated production of a Higgs boson decaying into bottom quarks and a weak vector boson decaying leptonically at NNLO in QCD [PDF]
Journal of High Energy Physics, 2019 We present the calculation of next-to-next-to-leading order (NNLO) corrections in perturbative QCD for the production of a Higgs boson decaying into a pair of bottom quarks in association with a leptonically decaying weak vector boson: pp→VH+X→ℓℓ¯bb¯+X ...

Journal of High Energy Physics, 2019 A search is presented for a charged Higgs boson heavier than the top quark, produced in association with a top quark, or with a top and a bottom quark, and decaying into a top-bottom quark-antiquark pair.

Zooming into CP violation in B (s) → hh decays
Journal of High Energy Physics, 2023 The LHCb collaboration has recently reported the first observation of CP violation in the penguin-dominated B s 0 $$ {B}_s^0 $$ → K − K + decay and further new measurements, indicating differences between the direct CP asymmetries of both the B s 0 $$ {B}

Study of two-body doubly charmful baryonic B decays with SU(3) flavor symmetry
Journal of High Energy Physics, 2023 Within the framework of SU(3) flavor symmetry, we investigate two-body doubly charmful baryonic B → B c B ¯ c ′ $$ B\to {\textbf{B}}_c{\overline{\textbf{B}}}_c^{\prime } $$ decays, where B c B ¯ c ′ $$ {\textbf{B}}_c{\overline{\textbf{B}}}_c^{\prime } $$
