Amplitude analysis of the D+s â Ï-Ï+Ï+ decay
A Dalitz plot analysis of the D-s(+) -> pi(-)pi(+)pi(+) decay is presented. The analysis is based on proton-proton collision data recorded by the LHCb experiment at a centre-of-mass energy of 8TeV and corresponding to an integrated luminosity of 1.5 fb(-1).

Kind of Weak Separation Axioms by D_ω,D_(α-ω),D_(pre-ω),D_(b-ω) and D_(β-ω)-Sets
 In this paper we define new types of sets we call them sets and use them to define some associative separation axioms. Some theorems about the relation between them and the weak separation axioms introduced in [5] are proved, with some other simple theorems.

First observation of π-K+ and π+K- atoms, their lifetime measurement and πK scattering lengths evaluation. [PDF]
he Low Energy QCD allows to calculate the $\pi\pi$ and $\pi K$ scattering lengths with high precision. There are accurate relations between these scattering lengths and $\pi^+\pi^-$, $\pi^-K^+$, $\pi^+K^-$ atoms lifetimes. The experiment on the first observation of $\pi^-K^+$ and $\pi^+K^-$ atoms is described.

Observation of the Ïð3686ß decays into Σ+ Σ - Ï and Σ+ Σ - Ï
Based on (2712.4 +/- 14.3) x 106 events recorded at the psi(3686) nominal mass collected with the BESIII detector operating at the BEPCII collider, the psi(3686) -> E +/- E over bar -omega and E +/- E over bar -phi decays are observed for the first time with statistical significances of 13.8 sigma and 7.6 sigma, respectively.

Search for a scalar partner of the X(3872) via Ï(3770) decays into γηη' and γÏ+ Ï- J/Ï
Using a data sample corresponding to an integrated luminosity of 2.93 fb(-1) collected at a center-of-mass energy of 3.773 GeV with the BESIII detector at the BEPCII collider, we search for a scalar partner of the X(3872), denoted as X(3700), via psi(3770) gamma eta eta' and gamma pi(+)pi(-)J/psi processes.

(ï³,ï´)- Strongly Derivations Pairs on Rings
Let R be an associative ring. In this paper we present the definition of (s,t)- Strongly derivation pair and Jordan (s,t)- strongly derivation pair on a ring R, and study the relation between them. Also, we study prime rings, semiprime rings, and rings that have commutator left nonzero divisior with (s,t)- strongly derivation pair, to obtain a (
