AbstractAbstract
[en] Some properties of structure functions are found on the basis of perturbative QCD. These properties reflect the relation between sea quarks and gluons and, therefore, may be of a more general nature. The properties of several sets of phenomenological structure functions of a proton are analyzed, and it is shown that each set is in agreement with theoretical predictions in those regions of x and Q2 values where direct experimental data were used. Beyond the experimentally studied region, some deviations appear, which can be used to estimate the region of admissible extrapolation of the set under consideration until new experimental data become available. 13 refs., 6 figs

AbstractAbstract
[en] We first review a parton-language derivation of the photon structure function ''anomaly''. More recent higher order calculations show similar growth with Q2 at all x, and experimenters are urged to obtain enough data to separate the x and Q2 dependence. When this behavior is coupled with Bloom-Gilman duality, we find that the ''ß excitation'' form factors of the photon are expected to have different Q2 behavior from those of hadrons

AbstractAbstract
[en] We report on some results we get from fits of the Lopez-Yndurain parametrizations for structure functions to old CDHS and EMC data. These parametrizations are compatible with QCD, to leading order, at the end points and the relevant sum rules are properly imposed. (author)

AbstractAbstract
[en] A family of multi-parameter, polynomially deformed oscillators (PDOs) given by the polynomial structure function ψ(n) is studied from the viewpoint of being (or not) in the class of Fibonacci oscillators. These obey the Fibonacci relation/property (FR/FP) meaning that the nth level energy En is given linearly, with real coefficients, by the two preceding ones En-1, En-2. We first prove that the PDOs do not fall in the Fibonacci class. Then, three different paths of generalizing the usual FP are developed for these oscillators: we prove that the PDOs satisfy the respective k-term generalized Fibonacci (or 'k-bonacci') relations; for these same oscillators we examine two other generalizations of the FR, the inhomogeneous FR and the 'quasi-Fibonacci' relation. Extended families of deformed oscillators are studied as well: the (q; μ)-oscillator with ψ(n) quadratic in the basic q-number [n]q is shown to obey the Tribonacci relation, while the (p, q; μ)-oscillators with ψ(n) quadratic (cubic) in the p, q-number [n]p,q are proven to obey the Pentanacci (Nine-bonacci) relations. Oscillators with general ψ(n), polynomial in [n]q or [n]p,q, are also studied.

AbstractAbstract
[en] We calculate the first moment of the photon structure function, < x>γ=∫01dxF2γ(x,Q2), on the quenched lattices with β=6.0 using the formalism developed by the authors recently. In this exploratory study, we take into account only the connected contractions. The result is compared with the experimental data as well as model predictions

AbstractAbstract
[en] If a nucleus is regarded as a collection of quasi-free nucleons, the nuclear structure functions are simply proportional to the corresponding structure functions of the nucleon. It has been argued that the conventional picture of the nucleus might not hold when the nucleus is probed during a very short time. A simple parton model has been formulated, illustrating the idea of an anomalous behaviour of nuclear structure functions. The nucleus is pictured as one bag of partons

AbstractAbstract
[en] A scattering by colorless multiquark formations in nuclei can explain the observation that the ratio of the structure functions of different nuclei is not unity. In the model proposed here a nucleus may contain a superfast quark, which could carry the entire momentum of the nucleus in the extreme case
