در این پایان نامه یکی از متون ادبی دوره بازگشت، یعنی "پریشان قاآنی " از نظر مباحث دستوری (ساختمان جمله و فعل) در دو فصل بررسی گردیده است. در فصل اول، ساختمان جمله های "پریشان" از ساده ترین جمله (دو جزیی) تا جمله های مرکب چند فراکردی، با ترسیم نمودار درختی، بررسی گردیده و در فصل دوم فعلهای "پریشان" از نظر ساختاری (ساده، مرکب، پیشوندی، پیشوندی مرکب، عبارت فعلی، ناگذر یک شخصه) بررسی و تبیین شده اس...

We present the growth of single wall carbon nanotubes (SWCNTs) from organic solvents such as benzene and toluene inside a host SWCNT. The solvents encapsulated in SWCNTs are transformed to an inner tube when subject to a heat treatment under dynamic vacuum at 1270 C. We used isotope labeling of the different carbon sources to prove that the source of the inner tubes is indeed the solvent. Our r...

The interference between the Pomeron and possible odderon mechanisms of diffractive π+π− photoproduction results in charge asymmetry of the produced pions. The observation of charge asymmetry of pions at moderate Mπ+π− will be an undoubted signal of odderon existence. To make numeral estimates more definite, we limit ourselves by the region Mπ+π− = 1.1 ÷ 1.5 GeV, where in the odderon mechanism ...

We estimate the di-photon coupling of f0(600), f0(980) and f2(1270) resonances in a coupled channel dispersive approach. The f0(600) diphoton coupling is also reinvestigated using a single channel T matrix for ππ scattering with better analyticity property, and it is found to be significantly smaller than that of a q̄q state. Especially we also estimate the di-photon coupling of the third sheet ...

Collisions in the asteroid belt frequently lead to catastrophic breakups, where more than half of the target's mass is ejected into space. Several dozen large asteroids have been disrupted by impacts over the past several billion years. These impact events have produced groups of fragments with similar orbits called asteroid families. Here we report the discovery of a very young asteroid family...

Final state interactions in the S–wave ππ system (I=0,2) are reexamined on the basis of the Omnès-Muskhelishvili equation and the coupled channel formalism. The contributions to the pion scalar form factor from ρ and f 2 (1270) exchange in the t–channel and from the f 0 (980) s–channel resonance are separately evaluated and the role of the nontrivial polynomial in the Omnès function in a couple...

The masses of the K1( 3P1) and K1( 1P1) are considered in a nonrelativistic constituent quark model, and the absolute value of the K1( 3P1) −K1(P1) mixing angle is determined to be about 59.29◦. Comparison of the theoretical predictions on the strong decay widths of the K1(1270) and K1(1400) in the 3P0 decay model as well as the production ratio of these two states in the τ decay between the av...
