Quark Flavor and Precision Measurements: QFL 4I

There is a significant gap between the inclusive measurement of the $B \rightarrow X_{c} l \nu$ branching fraction and the sum of the measurements of the exclusive $B \rightarrow X_{c} l \nu$ channels. The dominant contributions $B \rightarrow D^{*} l \nu$ and $B \rightarrow D l \nu$ are precisely known but the branching fractions of $B \rightarrow D^{**} l \nu$ have higher uncertainties....
We report the first search of CP violation using T-odd triple product asymmetries and the most precise branching fraction measurement for the singly Cabibbo suppressed decay $D^{0}\rightarrow K_{s}^{0} K_{s}^{0} \pi^{+} \pi^{-}$. These results will be obtained using $922\,{\rm fb}^{-1}$ data sample that was collected with the Belle detector at the KEKB asymmetric energy $e^+ e^-$ collider. The...
We study flavor–conserving M1 radiative decays of heavy flavor bottom baryons in the framework of Effective Mass Scheme (EMS) within the quark model. The intent of the EMS lies in the fact that the masses of the quarks inside the baryon are modified as a consequence of one-gluon exchange interaction with the spectator quarks and it treats all the quarks at the same footing. The baryon mass can...
We present measurements of the branching fractions and $CP$ asymmetries for $D_s^{+} \rightarrow K^{+} \eta $, $D_s^{+} \rightarrow K^{+} \pi^0 $, and $D_s^{+} \rightarrow \pi^{+} \eta $ decays, and the branching fraction for $D_s^{+} \rightarrow \pi^{+} \pi^0$ based on the full data sample collected by the Belle detector at the KEKB $e^+e^-$ asymmetric-energy collider. No evidence for $CP$...
A measurement of the $B_S^0\rightarrow J/\psi\phi$ decay parameters using $80~\mathrm{fb}^{-1}$ of integrated luminosity collected with the ATLAS detector from $13~\mathrm{TeV}$ proton-proton collisions at the LHC is presented. The measured parameters include the CP-violating phase $\phi_S$, the width difference $\Delta\Gamma_S$ between the $B_S^0$ meson mass eigenstates and the average...
Many analyses in ATLAS rely on the identification of jets containing $b$-hadrons ($b$-jets) with high efficiency while rejecting more than 99% of non-$b$-jets. Identification algorithms, called $b$-taggers, exploit $b$-hadron properties such as their long lifetime, their high mass, and high decay multiplicity. Recently developed ATLAS $b$-taggers using neural networks are expected to...
The data set provided by the Large Hadron Collider, with an integrated luminosity of 139.0 fb$^{-1}$ at a center-of-mass energy of $\sqrt{s}=13$ TeV, opens a window to search for new physics beyond the Standard Model (BSM). Searches for a resonance in the dijet mass spectrum are powerful probes of many BSM theories. For particles decaying into light-flavor quarks, inclusive searches provide...
