“…At present, the QCD multiparton matrix elements have been computed to double logarithmic accuracy in the small-x region [1][2][3]. They can be used to study the structure of hadronic final states in small-x processes, thus predicting some new distinctive features [1][2][3] such as the increase of particle multiplicity and the suppression of large rapidity gaps. Only some phenomenological investigations have been carried out [4], and more detailed analyses are needed.…”

“…(2.15). This so-called anomalous contribution [14] comes from ordering of transverse momenta that are opposite to that in the ordinary Altarelli-Parisi evolution of the structure function. We have found that in the small x limit and for fixed (albeit large) Q 2 , that it gives a contribution to the E T flow equal to that arising from the normal strong-ordering.…”

The distribution of transverse energy, E T , which accompanies deep-inelastic electron-proton scattering at small x, is predicted in the central region away from the current jet and proton remnants. We use BFKL dynamics, which arises from the summation of multiple gluon emissions at small x, to derive an analytic expression for the E T flow. One interesting feature is an x −ǫ increase of the E T distribution with decreasing x, where ǫ = (3α s /π)2 log 2. We perform a numerical study to examine the possibility of using characteristics of the E T distribution as a means of identifying BFKL dynamics at HERA.

“…The SAID output is applicable for both low-energy studies (spectroscopy) and high-energy research as well. For instance, the theoretical interpretation of DIS experimental results for target fragmentation, as well as for many other strong interaction processes, may be considered either in quark-gluon terms of QCD [82][83][84] or in hadronic terms. (It might be very interesting to investigate their interconnections.)…”

Over the past two decades, meson photo-and electroproduction data of unprecedented quality and quantity have been measured at electromagnetic facilities worldwide. By contrast, the meson-beam data for the same hadronic final states are mostly outdated and largely of poor quality, or even nonexistent, and thus provide inadequate input to help interpret, analyze, and exploit the full potential of the new electromagnetic data. To reap the full benefit of the high-precision electromagnetic data, new high-statistics data from measurements with meson beams, with good angle and energy coverage for a wide range of reactions, are critically needed to advance our knowledge in baryon and meson spectroscopy and other related areas of hadron physics. To address this situation, a stateof-the-art meson-beam facility needs to be constructed. The present paper summarizes unresolved issues in hadron physics and outlines the vast opportunities and advances that only become possible with such a facility.
