HFLAV $τ$ branching fractions fit and measurements of Vus with $τ$ lepton data

open access: yesSciPost Physics Proceedings, 2019
We report the status of the Heavy Flavour Averaging Group (HFLAV) averages of the $\tau$ lepton measurements We then update the latest published HFLAV global fit of the $\tau$ lepton branching fractions (Spring 2017) with recent results by BABAR.

Latest Belle results on Tau decays

open access: yesSciPost Physics Proceedings, 2019
We present preliminary results of a latest measurement at Belle, the branching fraction of rare tau decay, $\tau^- \rightarrow \pi^- \nu_{\tau} \ell^+ \ell^-$ ($\ell = e$ or $\mu$), using a 562 $\rm fb^{-1}$\ data set.

Search for the decay B 0 → ϕμ + μ −

open access: yesJournal of High Energy Physics, 2022
A search for the decay B 0 → ϕμ + μ − is performed using proton-proton collisions at centre-of-mass energies of 7, 8, and 13 TeV collected by the LHCb experiment and corresponding to an integrated luminosity of 9 fb −1. No evidence for the B 0 → ϕμ + μ −

Prefractal as the source of new rational approximations of functions with a fractal representation

open access: yesНаука. Инновации. Технологии, 2022
The Article is devoted to the problem of accelerating the convergence of polynomial and rational approximations of functions. In the theory of approximation of functions often used the idea of reducing the interval change in the argument as a method to ...

Study of J/ψ and ψ(3686)→Σ(1385)0Σ¯(1385)0 and Ξ0Ξ¯0

open access: yesPhysics Letters B, 2017
We study the decays of J/ψ and ψ(3686) to the final states Σ(1385)0Σ¯(1385)0 and Ξ0Ξ¯0 based on a single baryon tag method using data samples of (1310.6±7.0)×106 J/ψ and (447.9±2.9)×106 ψ(3686) events collected with the BESIII detector at the BEPCII ...

Observation of the semileptonic decay B + → p p ¯ μ + ν μ $$ {B}^{+}\to p\overline{p}{\mu}^{+}{\nu}_{\mu } $$

open access: yesJournal of High Energy Physics, 2020
The Cabibbo-suppressed semileptonic decay B + → p p ¯ μ + ν μ $$ {B}^{+}\to p\overline{p}{\mu}^{+}{\nu}_{\mu } $$ is observed for the first time using a sample of pp collisions corresponding to an integrated luminosity of 1.0, 2.0 and 1.7 fb −1 at centre-

Measurement of the absolute branching fraction of Λc+→pKS0η decays

open access: yesPhysics Letters B, 2021
Based on 586 pb−1 of e+e− annihilation data collected at a center-of-mass energy of s=4.6GeV with the BESIII detector at the BEPCII collider, the absolute branching fraction of Λc+→pKS0η decays is measured for the first time to be B(Λc+→pKS0η)=(0.414±0 ...

Measurement of the inclusive branching fraction for ψ(3686)→KS0+anything

open access: yesPhysics Letters B, 2021
Using 5.9 pb−1 of e+e− annihilation data collected at center-of-mass energies from 3.640 to 3.701 GeV with the BESIII detector at the BEPCII Collider, we measure the observed cross sections of e+e−→KS0X (where X=anything).
