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 ...

Search for the rare decays $B^{0}\to J/\psi \gamma$ and $B^{0}_{s} \to J/\psi \gamma$ [PDF]

open access: yes, 2015
A search for the rare decay of a $B^{0}$ or $B^{0}_{s}$ meson into the final state $J/\psi\gamma$ is performed, using data collected by the LHCb experiment in $pp$ collisions at $\sqrt{s}=7$ and $8$ TeV, corresponding to an integrated luminosity of 3 fb$^

Λ b →Λ ℓ + ℓ - form factors, differential branching fraction, and angular observables from lattice QCD with relativistic b quarks [PDF]

open access: yes, 2016
Using ($2+1$)-flavor lattice QCD, we compute the 10 form factors describing the ${\mathrm{\ensuremath{\Lambda}}}_{b}\ensuremath{\rightarrow}\mathrm{\ensuremath{\Lambda}}$ matrix elements of the $b\ensuremath{\rightarrow}s$ vector, axial vector, and ...

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 −

Measurement of B→Ds(*)+D*(*) branching fractions [PDF]

open access: yesPhysical Review D, 2000
This article describes improved measurements by CLEO of the $B^0 \to D_s^+ D^{*-}$ and $B^0 \to D_s^{*+} D^{*-}$ branching fractions, and first evidence for the decay $B^+ \to D_s^{(*)+} \bar{D}^{**0}$, where $\bar{D}^{**0}$ represents the sum of the $\bar{D}_1(2420)^0$, $\bar{D}_2^*(2460)^0$, and $\bar{D}_1(j=1/2)^0$ L=1 charm meson states.

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 ...

Measurement of the absolute branching fraction of D∗s0(2317)±→π0D±s [PDF]

open access: yes, 2017
The process e(+)e(-) -> D*D-+(s)*(s0) (2317)(-) + c.c. is observed for the first time with the data sample of 567 pb(-1) collected with the BESIII detector operating at the BEPCII collider at a center-of-mass energy root s = 4.6 GeV.

FRACTIONAL PROCESSES: FROM POISSON TO BRANCHING ONE [PDF]

open access: yesInternational Journal of Bifurcation and Chaos, 2008
Fractional generalizations of the Poisson process and branching Furry process are considered. The link between characteristics of the processes, fractional differential equations and Lèvy stable densities are discussed and used for the construction of the Monte Carlo algorithm for simulation of random waiting times in fractional processes.

Observation of $\eta^{\prime}\to\omega e^{+} e^{-}$ [PDF]

open access: yes, 2015
Based on a sample of \etapr mesons produced in the radiative decay $J/\psi\to\gamma\eta^{\prime}$ in $1.31\times 10^9$ $J/\psi$ events collected with the BESIII detector, the decay $\eta^{\prime}\to\omega e^{+} e^{-}$ is observed for the first time, with
