We study the effects of threshold resummation on the rapidity dependence of singleparticle-inclusive cross sections, using the prompt photon cross section as an example. We make use of the full resummation formula at next-to-leading logarithmic accuracy and develop a new technique for treating rapidity in resummation. We compare our phenomenological results with those of previous studies and di...

The 23gPrr(n,2n) and the 235u(r,,.2n) ~roSSsection are estimated by aPPIYing unit arit y in several approaches: a subtraction method and also by using a ratio approach that relates the above cross sections to the 23sU(n,2n) cross 239pu(n,@ cross section tO the section and the 235U(n)2n) cross section, respectively. Also, a self-consistent, simultaneous analysis of the cross section data of four...

The presence of 2γ-exchange in electron proton elastic scattering is discussed. From C-invariance and crossing symmetry, 2γ contribution induces a specific dependence of the reduced cross section on the variable ǫ. No evidence of such dependence exists in the available experimental data.

In this article free vibration of a Timoshenko nanobeam with variable cross-section is investigated using nonlocal elasticity theory within the scope of continuum mechanics. Small scale effects are modelled after Eringen’s nonlocal elasticity theory while the non-uniformity is presented by exponentially varying width through the beam length with constant thickness. Analytical solution is achiev...
