The aim of the present work is to introduce the concept of $lambda _{r}$-almost convergence of sequences. We define the spaces $fleft( lambda _{r}right) $ and $f_{0}left( lambda _{r}right) $ of $ lambda _{r}$-almost convergent and $lambda _{r}$-almost null sequences. We investigate some inclusion relations concerning those spaces with examples and we determine the $beta $- and $gamma $-duals of...

The interaction of the pseudoscalar meson and baryon octet is investigated by solving Bethe-Salpeter equation in infinite finite volume respectively. It found that there a resonance state generated dynamically, which owns mass about 1550MeV large decay width 120-200MeV. This couples strongly to $\pi \Xi$ channel. Therefore, it might not correspond $\Xi(1620)$ particle announced Belle collaborat...

Recently, a covariant formulation of non-equilibrium phenomena in the context General Relativity was proposed order to explain from first principles observed accelerated expansion Universe, without need for cosmological constant, leading GREA theory. Here, we confront theory against latest data, including type Ia supernovae, baryon acoustic oscillations, cosmic microwave background (CMB) radiat...

We assess comprehensively the potential of galaxy cluster edges as a standard ruler in measuring cosmological distances and probing exotic physics. Confronting five alternative models with from near future Dark Energy Spectroscopic Instrument survey, we conclude that can serve promising probe to constrain beyond $\Lambda$CDM. Especially, constraining precision equation state dark energy is just...

In this work, we perform a systematic study of the mass spectra, root mean square(r.m.s.) radii and radial density distributions doubly charmed baryons $\Xi_{cc}$ $\Omega_{cc}$. The calculations are carried out in frame work Godfrey-Isgur (GI) relativized quark model, where baryon is regarded as real three-body system quarks. Our results show that excited energy with $\rho$-mode lower than thos...

The production cross section of prompt $\mathrm{\Lambda_{c}^{+}}$ charm baryons was measured with the ALICE detector at LHC midrapidity in proton-proton (pp) and proton-lead (p-Pb) collisions a centre-of-mass energy per nucleon pair $\sqrt{s_\mathrm{NN}} = 5.02$ TeV. $\rm {\overline{\Lambda}{}_c^-}$ were reconstructed hadronic decay channels \Lambda_{c}^{+} \rightarrow p K^{-}\pi^{+}$ \Lambda_{...

The transverse momentum spectra of the well-identified produced particles, $\pi^+$, $\pi^-$, $K^+$, $K^-$, $p$, $\bar{p}$, $K_s^0$, $\Lambda$, $\bar{\Lambda}$, $\Xi^-$, and $\Xi^+$ are analyzed in a statistical approach. From partition function grand-canonical ensemble, we propose generic expression for dependence chemical potential $\mu$ on rapidity $y$. Then, by fitting this to experimental r...

in this paper, we investigate the existence of positive solutions for the ellipticequation $delta^{2},u+c(x)u = lambda f(u)$ on a bounded smooth domain $omega$ of $r^{n}$, $ngeq2$, with navier boundary conditions. we show that there exists an extremal parameter$lambda^{ast}>0$ such that for $lambda< lambda^{ast}$, the above problem has a regular solution butfor $lambda> lambda^{ast}$, the probl...

We suggested that longitudinal polarization of Lambda produced in e + e − annihilation at LEP energies can provide useful information on hadronization mechanism in general and on testing the validity of different pictures for the spin content of baryon in describing the fragmentation process in particular. We present the results obtained from the calculations based on two very much different pi...
