$b \to s τ^{+} τ^{-}$ Physics at Future $Z$ Factories

Lingfeng Li, Tao Liu

$b \to s τ^{+} τ^{-}$ measurements are highly motivated for addressing lepton-flavor-universality (LFU)-violating puzzles such as $R_{K^{(*)}}$ anomalies. The anomalies of $R_{D^{(*)}}…

Jet Topology

Lingfeng Li, Tao Liu, Si-Jun Xu

We introduce persistent Betti numbers to characterize topological structure of jets. These topological invariants measure multiplicity and connectivity of jet branches at a given s…

Learning Physics at Future $e^{-} e^{+}$ Colliders with Machine

Lingfeng Li, Ying-Ying Li, Tao Liu +1

Information deformation and loss in jet clustering are one of the major limitations for precisely measuring hadronic events at future $e^{-} e^{+}$ colliders. Because of their dominance…

Cosmological Signatures of Superheavy Dark Matter

Lingfeng Li, Shiyun Lu, Yi Wang +1

We discuss two possible scenarios, namely the curvaton mechanism and the dark matter density modulation, where non-Gaussianity signals of superheavy dark matter produced by gravity…
