The current normalization of the cross section of inclusive high-p T particle production in deuteron-gold collisions measured at RHIC relies on Glauber model calculations for the inelastic dAu cross section. These calculations should be corrected for diffrac-tion. Moreover, they miss the Gribov's inelastic shadowing which makes nuclei more transparent (color transparency) and reduce the inelast...

This paper is devoted to a study of possible scaling laws, and their logarithmic corrections, occurring in deep inelastic electropion production. Both the exclusive and semiexclusive processes are considered. Scaling laws, originally motivated from PCAC and current algebra considerations are examined, first in the framework of the parton model and QCD peturbation theory and then from the more f...

These lectures include an introduction to the partonic description of the proton, the photon and the ‘colour singlet’, as seen in inclusive and semi-inclusive DIS, in e+e− collisions, and in diffractive processes, respectively. Their formal treatment using structure, fragmentation, and fracture functions is outlined giving an insight into the perturbative QCD framework for these functions. Exam...

Dynamics of inelastic gases are studied within the framework of random collision processes. The corresponding Boltzmann equation with uniform collision rates is solved analytically for gases, impurities, and mixtures. Generally, the energy dissipation leads to a significant departure from the elastic case. Specifically, the velocity distributions have overpopulated high energy tails and differe...

Inspired by the recent findings of the twoPþc states in the J=ψpmass spectrum at LHCb,we investigate the elastic and inelastic cross sections of the J=ψN, ηcN,ΥN and ηbN channelswithin the constraints fromheavy quark spin and flavor symmetry. The D̄ð ÞΣð Þ c (Bð ÞΣð Þ b ) bound states predicted in earlier works should be accessible in elastic and/or inelastic processes of the J=ψN and/or ηcN (ΥN...

We reanalyze deep inelastic scattering data of BCDMS Collaboration by including proper cuts of ranges with large systematic errors. We perform also the fits of high statistic deep inelastic scattering data of BCDMS, SLAC, NM and BFP Collaborations taking the data separately and in combined way and find good agreement between these analyses. We extract the values of the QCD coupling constant αs(...

O(α) QED radiative corrections to neutral current deep inelastic production of heavy quarks are calculated in the leading log approximation and compared with the corresponding corrections assuming a massless charm parton. Besides the inclusive case, corrections to the semi-inclusive dσ/dxdydz and the effect of z-cuts are studied. In the latter case, the massless corrections differ from the corr...

I review the status of next-to-leading-order calculations for hadronic final states in deeply-inelastic lepton–nucleon scattering. In more detail, I focus on calculations of (2+1)-jet-type cross sections, describe recent progress in extending the perturbative description into the transition region between deeply inelastic scattering and photoproduction, and study the validity of the fragmentati...

Visualising chemical reactions by X-ray methods is a tantalising prospect. New light sources provide the prospect for studying atomic, electronic and energy transfers accompanying chemical change by X-ray spectroscopy and inelastic scattering. Here we assess how this adventure can illuminate inorganic and catalytic chemistry. In particular X-ray inelastic scattering provides a means of exploiti...
