Description

Heavy Flavors and the CKM Matrix

126. BSM $B-\overline{B}$ mixing from lattice QCD

Felix Erben (University of Edinburgh)

8/30/22, 1:00 PM

Heavy Flavors and the CKM Matrix

Parallel session talk

We are presenting our ongoing lattice QCD study on $B-\overline{B}$ mixing on several RBC/UKQCD and JLQCD ensembles with 2+1 dynamical-flavour chirally symmetric domain wall fermions, including physical-pion-mass ensembles. The inverse lattice spacings range from a coarse 1.7 GeV to a very fine 4.5 GeV, allowing us to simulate near the b-quark mass. We extract bag parameters $B_{B_d}$ and...

318. CPV in Belle II

Radek Zlebcik (Charles University)

8/30/22, 1:30 PM

122. CPV measurements from LHCb

Andrea Villa (Universita e INFN, Bologna (IT))

8/30/22, 2:00 PM

Heavy Flavors and the CKM Matrix

Parallel session talk

A rich set of new results from the LHCb experiment are reported. Searches of CP violations in the beauty and charm sector have been performed with a variety of techniques offering new insights into the CP violation phenomenon. In this presentation, an updated status of charm-mixing parameters is also given. These measurements are of great importance to test the Standard Model's assumptions and...

321. Indirect bounds

Peter Stangl (University of Bern)

8/30/22, 3:30 PM

350. Probing BSM Physics in $B\to D^{\ast +}{\ell }^{-}\overline{\nu }$ Using Monte Carlo Simulation

Quinn Campagna

8/30/22, 4:00 PM

Parallel session talk

Several experimental measurements of $b$-decays have suggested the presence of physics beyond the Standard Model (BSM). One set of such measurements are the decay modes $B\to D^{\ast +}{\ell }^{-}\overline{\nu }$ with $\ell =e,\mu ,$ and $\tau$. A recent analysis of 2019 Belle data found $\mathrm{\Delta }{A}_{FB}=A_{FB}(B\to D^{\ast }\mu \nu )-A_{FB}(B\to D^{\ast }e\nu )$ to be
$4.1\sigma$ away from the SM prediction....

351. Belle II results on inclusive $B\to X\ell \nu$

Frank Meier (Duke University)

8/30/22, 4:30 PM

105. Inclusive semileptonic $B$ decays on the lattice

Sandro Maechler (Universities of Zurich and Turin)

8/30/22, 5:00 PM

Heavy Flavors and the CKM Matrix

Parallel session talk

One of the most persistent tensions in flavor physics is the $V_{cb}$ puzzle, a long standing tension between inclusive and exclusive determinations of the CKM matrix element $V_{cb}$. After lattice QCD has been applied extremely successfully in the calculation of physical quantities needed for the exclusive determination of $V_{cb}$ for many years, now also methods for computing inclusive...

98. CKM measurements from LHCb

Mrs Halime Sazak (LPC Clermont-Ferrand)

9/3/22, 3:30 PM

Heavy Flavors and the CKM Matrix

Parallel session talk

The CKM angle gamma determination through the tree-level is a standard candle measurement of CP violation in the Standard Model.
A new combination of all LHCb measurements is performed. A precision below four degrees is obtained, which dominates the world average.
The measurements on the precise determination of the CKM matrix elements Vcb and Vub whose ratio determines the length of the...

320. Exclusive semileptonic decays at Belle II

Philipp Horak

9/3/22, 4:00 PM

143. Semileptonic $B\to D^{\ast }$ Decay with Lattice QCD

Judd Harrison (University of Glasgow)

9/3/22, 4:30 PM

Heavy Flavors and the CKM Matrix

Parallel session talk

We present preliminary lattice QCD results from the HPQCD collaboration for the $B\to D^{\ast }$ form factors, including tensor form factors. We use these results to construct the differential decay rate, which we compare directly to experimental data. We also present a 'lattice only' determination of the ratio, $R(D^{\ast })=\mathrm{\Gamma }(B\to D^{\ast }\tau {\bar{\nu }}_{\tau })/\mathrm{\Gamma }(B\to D^{\ast }\mu {\bar{\nu }}_{\mu })$,...

349. Angular observables in semileptonic B decays

Alakabha Datta (University of Mississippi)

Parallel session talk

322. FLAG review on CKM matrix elements

Ruth Van de Water (Fermilab)

28. No show: ATLAS measurements of CP violation and rare decay processes with beauty mesons

ATLAS Collaboration

Heavy Flavors and the CKM Matrix

Parallel session talk

The ATLAS experiment has performed measurements of $B$-meson rare decays proceeding via suppressed electroweak flavour changing neutral currents, and of mixing and CP violation in the neutral $B_s^0$ meson system. This talk will focus on the latest results from the ATLAS collaboration, such as rare processes $B_s^0\to \mu \mu$ and $B_d^0\to \mu \mu$, and CP violation in $B^0_s \to J/\psi...

329. Place holder: New results on beauty, charm and taus from Belle II

Soeren Prell (Iowa State University)

Heavy Flavors and the CKM Matrix

Plenary talk

The Belle II experiment has collected e+e- collision data near the Upsilon(4S) resonance since 2019 at the SuperKEKB accelerator. Recent results from those data in beauty, charm and tau decays will be presented.
