CP Properties of Higgs Boson Interactions with Top Quarks in the tt¯H and tH Processes Using Hγγ with the ATLAS Detector

open access: yesPhysical Review Letters, 2020
A study of the charge conjugation and parity (CP) properties of the interaction between the Higgs boson and top quarks is presented. Higgs bosons are identified via the diphoton decay channel (H→γγ), and their production in association with a top quark pair (tt¯H) or single top quark (tH) is studied.

Precision measurements of Ds+ηe+νe and Ds+ηe+νe

open access: yesPhysical Review, 2023
Precision measurements of the semileptonic decays Ds+→ηe+νe and Ds+→η′e+νe are performed with 7.33 fb−1 of e+e− collision data collected at center-of-mass energies between 4.128 and 4.226 GeV with the BESIII detector. The branching fractions obtained are B(Ds+→ηe+νe)=(2.255±0.039stat±0.051syst)% and B(Ds+→η′e+νe)=(0.810±0.038stat±0.024syst ...

Search for the X(2370) and observation of ηcηηη in J/ψγηηη

open access: yesPhysical Review, 2021
Using a sample of 1.31×109 J/ψ events collected with the BESIII detector, we perform a study of J/ψ→γηηη′ to search for the X(2370) and ηc in the ηηη′ invariant mass distribution. No significant signal for the X(2370) is observed, and we set an upper limit for the product branching fraction of B(J/ψ→γX(2370)·B(X(2370)→ηηη′)<9.2×10−6 at the 90 ...

CP asymmetries of B¯Xs/Xdγ in models with three Higgs doublets

open access: yesPhysical Review, 2021
Direct CP asymmetries (ACP) in the inclusive decays of B¯→Xsγ and B¯→Xs+dγ of the order of 1% will be probed at the BELLE II experiment. In this work, three such asymmetries are studied in the context of a three-Higgs-doublet model (3HDM), and it is shown that all three ACP can be as large as the current experimental limits.

HZγ decay and CP violation

open access: yesPhysical Review
This study examines the impact of CP-violation on the signal strength μZγ, which was reported as 2.2±0.7 by the LHC. We obtain constraints on the real and absorptive parts of the CP-violating form factor h3Zγ and find that they are less than 1.15 GeV.

Loop-induced determinations of Vub and Vcb

open access: yesPhysical Review, 2022
We use loop induced processes like meson oscillations and rare b hadron decays to determine the absolute values of the Cabibbo-Kobayashi-Maskawa matrix elements |Vub| and |Vcb| and compare our results to the standard determinations based on inclusive and exclusive semileptonic tree-level decays of B mesons.

Probing an additional bottom Yukawa coupling via bgbAbZH signature

open access: yesPhysical Review, 2019
The recent discovery of the bottom quark Yukawa coupling (hbb) of the 125 GeV scalar motivates one to search for extra bottom Yukawa coupling that may exist in nature. The two Higgs doublet model without a discrete Z2 symmetry allows the possibility of additional bottom Yukawa coupling ρbb.
