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]

Higgs bosons in Left-Right symmetric Randall-Sundrum models

Here z is the extra-dimensional coordinate, and R is the inverse of the AdS curvature, k. Two branes define the boundaries of the extra dimension. One, at z = R, is called the UV, or Planck, brane. The other, at z = R, is the IR, or TeV, brane. Picking R = (MPlanck/Melectroweak)R, which is natural in realistic stabilization mechanisms, solves the hierarchy problem [3]. In the original RS model ...

Light composite vector bosons.

In gauge theories with slowly-running coupling constants, it may be possible for four-fermion operators to be nearly marginal. Such operators can possess asymptotically weak couplings, and can plausibly give rise to light composite vector mesons. † On leave from the Centre d’Etudes de Saclay, F-91191 Gif-sur-Yvette cedex, France CERN-TH.6767/92 December, 1992 The so-called Standard Model of acc...

Composite Weak Bosons: a Lattice Analysis

The Standard Model [1] (SM) describes the strong, weak and electromagnetic interactions by a gauge theory based on the group GSM = SU(3) × SU(2) × U(1) which is broken by the Higgs mechanism to SU(3)×U(1). The theory is essentially determined once the matter fields and their transformation under the local gauge transformations of GSM are specified. The matter fields (leptons and quarks) and the...

A novel left - right symmetric model

A novel gauge model which has a spontaneously broken parity symmetry is constructed. The model has only 2 parameters beyond those of the standard model. Some of the unusual implications of the model are discussed. 1 Email: [email protected] The standard model of particle physics (SM) is an extremely successful description of past and existing experiments. At present there is no experim...
