The reaction γ + p → K + + Σ + π was used to determine the invariant mass distributions or " line shapes " of the Σ + π − , Σ − π + and Σ 0 π 0 final states, from threshold at 1328 MeV/c 2 through the mass range of the Λ(1405) and the Λ(1520). The measurements were made with the CLAS system at Jefferson Lab using tagged real photons, for center-of-mass energies 1.95 < W < 2.85 GeV. The three ma...
A high-throughput screening (HTS) method based on fluorescence imaging (FI) was implemented to evaluate the catalytic performance of selenide-modified nano-TiO2. Chemical ink-jet printing (IJP) technology was reformed to fabricate a catalyst library comprising 1405 (Ni(a)Cu(b)Cd(c)Ce(d)In(e)Y(f))Se(x)/TiO2 (M6Se/Ti) composite photocatalysts. Nineteen M6Se/Tis were screened out from the 1405 can...
An effective low energy Lagrangian density is applied to nuclear K−-dynamics. The free parameters, local s-wave couplings and SU(3)-symmetry constrained range terms are adjusted to describe elastic and inelastic K−-nucleon scattering data. The propagation and decay of the Λ(1405)-resonance and the Λ(1405)-nucleon hole state is studied self consistently with respect to the K−-propagation in isos...
Abstract We evaluate the decay width for the processes f1(1285)→ πa0(980) and f1(1285)→ πf0(980) taking into account that all three resonances are dynamically generated from the meson-meson interaction, the f1(1285) from K ∗K̄ − c.c and the a0(980), f0(980) from πη,KK̄ and ππ,KK̄ respectively. We use a triangular mechanism similar to that of the η(1405) → ππη, which provides a decay width for f1(1...
مقوله مسکن گسترده وپیچیده است ابعاد متنوعی دارد. ونمی توان تعریف واحدی از آن ارائه کرد.مسکن یک مکان فیزیکی است وبه عنوان سرپناه نیاز اولیه واساسی خانوار به حساب می آید. مسئله مسکن امروزه از مسائل پیچیده کشورها منجمله کشور ما می باشد. مسکن به عنوان یکی از نیازهای اساسی انسان و یکی از معیارهای سنجش توسعه یافتگی محسوب می شود. در حال حاضر، مسأله ای که راجع به مسکن در سطح جهانی از آن صبحت می شود، م...
for a composition $lambda$ of $n$ our aim is to obtain reduced forms for all the elements in the kazhdan-lusztig (right) cell containing $w_{j(lambda)}$, the longest element of the standard parabolic subgroup of $s_n$ corresponding to $lambda$. we investigate how far this is possible to achieve by looking at elements of the form $w_{j(lambda)}d$, where $d$ is a prefix of an element...
We investigate the negative-parity baryon spectra in quenched lattice QCD. We employ the anisotropic lattice with standard Wilson gauge and O(a) improved Wilson quark actions at three values of lattice spacings with renormalized anisotropy ξ = aσ/aτ = 4, where aσ and aτ are spatial and temporal lattice spacings, respectively. The negative-parity baryons are measured with the parity projection. ...
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...
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...
