in this paper, we introduce new classes $sum_{k,p,n}(alpha ,m,lambda ,l,rho )$ and $mathcal{t}_{k,p,n}(alpha ,m,lambda ,l,rho )$ of p-valent meromorphic functions defined by using the extended multiplier transformation operator. we use a strong convolution technique and derive inclusion results. a radius problem and some other interesting properties of these classes are discussed.

In this paper, we study the decomposition of semirings with a semilattice additive reduct. For, we introduce the notion of principal left $k$-radicals $Lambda(a)={x in S | a stackrel{l}{longrightarrow^{infty}} x}$ induced by the transitive closure $stackrel{l}{longrightarrow^{infty}}$ of the relation $stackrel{l}{longrightarrow}$ which induce the equivalence relation $lambda$. Again non-transit...

for any lacunary sequence $theta = (k_{r})$, we define the concepts of $s_{theta}-$limit point and $s_{theta}-$cluster point of a sequence of fuzzy numbers $x = (x_{k})$. we introduce the new sets  $lambda^{f}_{s_{theta}}(x)$, $gamma^{f}_{s_{theta}}(x)$ and prove some inclusion relaions between these and the sets $lambda^{f}_{s}(x)$, $gamma^{f}_{s}(x)$ introduced in ~cite{ayt:slpsfn} by aytar [...

Excited neutral hyperons Y 0∗ produced in the pp → pKY 0∗ reaction with a COSY beam momentum of 3.65 MeV/c have masses below 1540 MeV/c. The ANKE spectrometer allows the simultaneous observation of different decay modes: Y 0∗ → πΣ, π∓Σ±, π0Λ,K−p by measuring kaons and pions of either charge in coincidence with protons. We have found indications for a neutral excited hyperon resonance Y 0∗ with ...

The study of rare resonances with strange content produced in p+p and p+Nb collisions at 3.5 GeV kinetic energy has recently been addressed by the HADES collaboration at GSI. Here we present the results obtained for the Σ(1385) resonance produced in p+p collisions at 3.5 GeV. The spectral function and the differential cross-section of the resonance could be evaluated. With a nominal mass of 138...

The main features of nuclear reactions with participation of baryon resonances (∆(1232), S(1535) and Λ(1405)), which are interpreted as a manifestation of the bound states of nucleus and corresponding meson

The strong decays of excited nonstrange baryons into the final states ΛK, ΣK, and for the first time into Λ(1405)K, Λ(1520)K, Σ(1385)K, ΛK∗, and ΣK∗, are examined in a relativized quark pair creation model. The wave functions and parameters of the model are fixed by previous calculations of Nπ and Nππ, etc., decays. Our results show that it should be possible to discover several new negative pa...

The s-wave meson-baryon interaction in the S = −1 sector is studied by means of coupled-channels, using the lowest-order chiral Lagrangian and the N/D method to implement unitarity. The loops are regularized using dimensional renormalization. In addition to the previously studied Λ(1405), employing this chiral approach leads to the dynamical generation of two more s-wave hyperon resonances, the...

We study the γp → K+Λ(1405) reaction at energies close to threshold using a chiral unitary model where the resonance is generated dynamically from Kp interaction with other channels constructed from the octets of baryons and mesons. Predictions are made for cross sections into several channels and it is shown that the detection of the K+ is sufficient to determine the shape and strength of the ...
