摘要:

AbstractWe give a comprehensive review of the polarization asymmetries predicted by QCD and the parton model for hard processes. The article discusses the interrelation between these processes which include deep inelastic inclusive, massive lepton pairs, reflected and transmitted asymmetries in hadron production at largepT, prompt photon production, etc. We also discuss the validity of the formulae derived and the potential effects of non‐leading logarithmic and power order

摘要:

AbstractA quantum theory of intrinsicallyextendedparticles similar to de Broglie's Theory of the Double Solution is proposed. A rational notion of the particle's extension is enthroned by realizing its internal structure viasoliton‐typesolutions ofnonlinear, relativistic wave equations. Thesedroplet‐typewaves have a quasi‐objective character except for certain boundary conditions which may be subject to stochastic fluctuations. More precisely, this assumption amounts to a probabilistic description of thecenterof a soliton such that it would follow the conventional quantum‐mechanical formalism in the limit of zero particle radius. At short interaction distances, however, a promising nonlinear andnonlocaltheory emerges. This model is not only capable of achieving a conceptually satisfying synthesis of the particle‐wave dualism, but may also lead to arationalresolution of epistemological problems in the quantum‐theoretical measurement process. Within experimental errors the results for, e.g., the hydrogen atom can be reproduced by appropriately specifying the nature of the nonlinear self‐interaction. It is speculated that field theoretical issues raised by such notions as identical particles, field quantization and renormalization are already incorporated or resolved by this nonlocal theory, at least
