Inclusive forward-backward asymmetry for light quarks.
The energy-differential forward-backward asymmetry in the reaction {ital e}{sup +}{ital e}{sup {minus}}{r arrow}M+ anything, {ital M} being a leading, light-quark-constituted meson in a jet, is considered. The measurement of this quantity yields rank-1 and higher-rank fragmentation functions for light quarks hadronizing into light mesons, separately. It is also possible, in the case of a large event sample and good particle identification capabilities at high energies, to obtain information on {ital Z} couplings to light quarks.

Infrared fixed point of the top Yukawa coupling in split supersymmetry
The severe constraints imposed on the parameter space of the minimal split supersymmetry model by the infrared fixed point solution of the top Yukawa coupling Yt are studied in detail in terms of the value of the top quark mass measured at the Tevatron together with the lower bound on the lightest Higgs mass established by LEP. The dependence of the higgsino mass parameter

Parton description of the forward peak in single particle electroproduction with highly virtual photons
The parton mode or the reaction eN→eAB (N = nucleon, A, B = hadrons) in the fixed ω Bj limit is used to discuss the width of the corresponding forward peak as a function of the photon mass.

An operatorially solved model of massless two-dimensional quantum chromodynamics
An operator solution is constructed in (1,1) dimensions to the massless quantum chromodynamics of n fermion quarks and n2 − 1 vector boson gluons with local colour SU(n) symmetry. The interacting quark field is a confined SU(n) Thirring field with zero Abelian coupling. The colour gluons are dependent Lie fields obeying the gluon-free fermionic current identity. Explicit local infinitesimal operator colour transformations (with an arbitrary coordinate-independent Lorentz vector coefficient defining the gauge) are given and the requirement of proper colour covariance linked to the vanishing of the coloured quark source currents and hence to the absence of coloured quark-composite states. The status of Noether's theorem is also clarified.
