In the year 2000 the four LEP experiments have collected 870 pb-1 of data at energies between 200 and 209 GeV, with about 510 pb-1 above 206 GeV. These data have been combined with data sets collected earlier at lower energies. %The following 95% confidence level bounds have been obtained. For charged Higgs bosons predicted by two-doublet extensions of the Standard Model and decaying only into the channels H+->csbar and tau+nutau, a lower mass bound of 78.6 GeV is obtained, at the 95% confidence level.

Searching for a Charged Higgs Boson in Top-Quark Decays via the $WZ$ Mode
hep-ph 2025-09 unverdicted novelty 7.0

Recasting ttZ analyses yields sub-permille constraints on Br(t→H±b)×Br(H±→WZ) and vΔ≲2 GeV in the Y=0 Higgs triplet model, accompanied by a 2σ preference for a non-zero signal.
Probing the imaginary parts and their $q^2$ dependences for the tau $g-2$ and EDM
hep-ph 2026-05 unverdicted novelty 5.0

Explores q² dependence and imaginary parts of tau g-2 and EDM in SMEFT and 2HDM, proposing methods to measure them at Belle II and STCF to improve a_τ bounds by over an order of magnitude.
