1452. The SM expectation for muon g-2

1350. $R_{D^{(*)}}$, $R_{K^{(*)}}$ and muon g-2 anomalies in RPV supersymmetry and the discovery prospect at LHC

BSM

In R-parity violating supersymmetric scenario, assuming the third-generation superpartners to be the lightest (calling the scenario RPV3), we show that there are some benchmark scenarios in which $R_{D^{(*)}}$ and / or $R_{K^{(*)}}$ and / or $(g-2)_{\mu}$ anomalies can be addressed and also can be detected at LHC 14 TeV or future 27 TeV hadron collider. We consider...

1234. Searches for lepton flavour and lepton number violation in K+ decays

Joel Christopher Swallow (University of Birmingham (GB))

BSM

The NA62 experiment at CERN collected a large sample of charged kaon decays into final states with multiple charged particles in 2016-2018. This sample provides sensitivities to rare decays with branching ratios as low as 10-11. Searches for lepton flavour and lepton number violating decays of the charged kaon into final states containing a lepton pair based on this data set are presented.

1278. Flavourful Feebly-Interacting Particles for flavour and g-2 anomalies

Flavor

Flavourful Feebly-Interacting Particles (FIPs) in the MeV to GeV range have a strong impact on precision frontier observables ranging from rare meson decays to the lepton anomalous magnetic moments. We use an effective field theory approach “SM+X” along with the HEPfit package to study the effect of FIPs on B to K observables. We present an updated study of the available parameter space and...

1356. New Contributions to Flavor Observables from Left-Right Symmetric Models with Universal Seesaw

Ritu Dcruz (Oklahoma State University)

Flavor

A Left-Right Symmetric Model which utilizes vector-like fermions to generate quark and lepton masses via universal see-saw mechanism is studied. In this talk, I will present the results of our analysis on the new contributions to flavor observables from this model. Further, I will discuss the possibilities of explaining the neutral current B-anomalies as well as the Cabibbo anomaly in this model.

1395. Explaining $g_{\mu}-2$ and $R_{K^{(*)}}$ using the light mediators of $U(1)_{T3R}$

Sumit Ghosh (Texas A&M University)

BSM

Scenarios in which right-handed light Standard Model fermions couple to a new gauge group, $U(1)_{T3R}$ can naturally generate a sub-GeV dark matter candidate. But such models necessarily have large couplings to the Standard Model, generally yielding tight experimental constraints. We show that the contributions to $g_\mu-2$ from the dark photon and dark Higgs largely cancel out in the narrow...

1195. Testing Lepton Flavor Universality at the Z Pole

LINGFENG LI (HKUST)

Flavor

$b\to s\tau\tau$ and $b\to c\tau \nu$ measurements are highly motivated for addressing lepton-flavor-universality-violating (LFUV) puzzles, such as $R_{D^{(*)}}$, $R_{J/\psi}$ and $R_{K^{(\ast)}}$ anomalies, raised by the data of LHCb, BELLE and BarBar. The planned operation of future $e^-e^+$ colliders as a $Z$ factory provides a great opportunity to conduct such measurements, because of its...
