The Excess of HERA High−Q Events and Leptoquarks in a Left-Right Symmetric Preon Model
An interpretation that the HERA excess events are due to intermediate production and decay of composite leptoquarks in the left-right symmetric preon model is given. Because of the preon-line rule, expected to be valid well, the event-ratio of neutral to charged current interactions is predicted to be one. [email protected]
متن کاملPreon Prophecies by the Standard Model
The Standard Model of quarks and leptons is, at first sight, nothing but a set of ad hoc rules, with no connections, and no clues to their true background. At a closer look, however, there are many inherent prophecies that point in the same direction: Compositeness in terms of three stable preons.
متن کاملA Preon Model from Manasson's Theory
V. Manasson has applied dissipative chaos theory to particle physics, deriving a simple relation between the fine structure constant and Feigenbaum delta constant. It is presented a preon model based on Manasson's theory. The model is intended as a naive toy one, as it makes use of unjustified assumptions, as e.g. the possibility of the existence of neither fermionic nor bosonic particles in 3+...
متن کاملAn Automatic Invisible Axion In The SUSY Preon Model
It is shown that the recently proposed preon model which provides a unified origin of the diverse mass scales and an explanation of family replication as well as of inter–family mass–hierarchy, naturally possesses a Peccei–Quinn (PQ) symmetry whose spontaneous breaking leads to an automatic invisible axion. Existence of the PQ–symmetry is simply a consequence of supersymmetry and the requiremen...
متن کاملLittle Groups of Preon Branes
Little groups for preon branes (i.e. configurations of branes with maximal (n-1)/n fraction of survived supersymmetry) for dimensions d=2,3,...,11 are calculated for all massless, and partially for massive orbits. For massless orbits little groups are semidirect product of d-2 translational group Td−2 on a subgroup of (SO(d-2) × R-invariance) group. E.g. at d=9 the subgroup is exceptional G2 gr...
