Diffractive parton distribution functions give the probability to find a parton in a hadron if the hadron is diffractively scattered. We provide an operator definition of these functions and discuss their relation to diffractive deeply inelastic scattering and to photoproduction of jets at HERA. We perform a calculation in the style of “constituent counting rules” for the behavior of these func...

We investigate differential electron momentum distributions in nonsequential double ionization with linearly polarized, few-cycle pulses, using a classical model based on a laser-assisted inelastic (e(-),2e(-)) rescattering mechanism. These yields, as functions of the momentum components parallel to the laser polarization, are highly asymmetric and strongly influenced by the phase difference be...

This Rapid Communication presents an analytical study of the bouncing of a completely inelastic ball on a vertically vibrated plate. The interplay of saddle-node and period-doubling bifurcations leads to an intricate structure of the bifurcation diagram with uncommon properties, such as an infinity of bifurcation cascades in a finite range of the control parameter Gamma. A pseudochaotic behavio...

We study the possible contribution of the nucleon’s virtual meson cloud to the sea quark distribution as observed in deep inelastic lepton scattering. We adjust the meson-nucleon cut-offs to the large-x tails of the antiquark distributions, find qualitatively different behavior in the flavor singlet and non-singlet channels and study the scale dependence of our results. We demonstrate that, wit...

We propose pure quantum parton model of soft interactions. The model is based on soft partons which interact eikonally and locally in a transverse plane. We directly construct S-matrix operator and partons Fock space using developed method of discretization of a transverse plane. Counting inelastic states we explicitly derive AGK cancellations and cutting rules from relation between inclusive a...

Purely rotational transitions of a molecule embedded in large He clusters have been detected for the first time. The saturation behavior shows that, in contrast to previous expectations, the microwave line profiles are dominated by inhomogeneous broadening mechanisms. Spectral holes and peaks produced by microwave-microwave double resonance have widths comparable to those of single resonance li...

High-statistics deep-inelastic scattering at the EIC can elucidate several open questions about the structure of nucleons and nuclei that cannot be answered solely by measurements at the Large Hadron Collider. These questions include avor composition of PDFs; nuclear correction factors; e ect of isospin violation on the PDFs; and behavior of the longitudinal structure function FL at the boundar...

We have measured differential cross sections (DCSs) for the vibrationally inelastic scattering process H + o-D(2)(v = 0, j = 0,2) --> H + o-D(2)(v' = 1-4, j' even). Several different collision energies and nearly the entire range of populated product quantum states are studied. The products are dominantly forward-scattered in all cases. This behavior is the opposite of what is predicted by the ...

It is well recognized that structures designed by current codes undergo large inelastic deformations during major earthquakes. However, lateral force distributions given in the seismic design codes are typically based on results of elastic response studies. In this paper, current code lateral force distributions are reviewed in view of the results obtained from nonlinear dynamic analyses of sev...

The Wigner formalism is a convenient reformulation of the Schr€odinger equation that allows the simulation of transient behavior of quantum systems in the presence of general boundary conditions. Recently, a Wigner Monte Carlo technique, based on particles signs, has been generalized to twodimensional evolution problems. In this paper, we apply this technique to study the time reversibility of ...
