Absence of Klein's paradox for massive spinless bosons coupled by a nonminimal vector interaction
(2009-12-01)
A few properties of the nonminimal vector interaction in the Duffin-Kemmer-Petiau theory in the scalar sector are revised. In particular, it is shown that the nonminimal vector interaction has been erroneously applied to ...
Covariance for electromagnetic current for two bosons at higher order in the light front
(2010-12-01)
We show that the electromagnetic current for a system composed by two charged bosons has a structure of many bodies even in the impulse approximation, when described in the time x +. In terms of the two body component for ...

Boson-boson bound states in higher-derivative electromagnetism augmented by a Chern-Simons term
(2006-01-01)
The Chern-Simons term alone is unable to form scalar Cooper pairs. Nonetheless, there exist charged-scalar-boson - charged-scalar-boson bound states in the framework of Maxwell-Chern- Simons theory. Numerical calculations ...
The strength of trilinear higgs boson coupling in composite models
(2007-10-01)
In this work we discuss the strength of the trilinear Higgs boson coupling in composite models in a model independent way. The coupling is determined as a function of a very general ansatz for the fermionic self-energy, ...
Limits on anomalous couplings from Higgs boson production at the Tevatron
(World Scientific Publ Co Pte Ltd, 1998-01-01)
We estimate the attainable limits on the coefficients of dimension-6 operators from the analysis of Higgs boson phenomenology, in the framework of a SUL(2) x U-Y(1) gauge-invariant effective Lagrangian. Our results, based ...
L-R asymmetries and signals for new bosons
(American Institute of Physics (AIP), 1999-01-01)
Several left-right parity violating asymmetries in lepton-lepton scattering in fixed target and collider experiments are considered as signals for doubly charged vector bosons (bileptons).
Double Higgs production at the LHC as a robust test of little Higgs models
(2006-02-08)
We analyze double Higgs boson production at the LHC in the context of Little Higgs models. In double Higgs production, the diagrams involved are directly related to those that cause the cancellation of the quadratic ...

Two-Q-boson interferometry and generalization of the Wigner function
(2004-12-02)
Bose-Einstein correlations of two identically charged Q-bosons are derived considering those particles to be confined in finite volumes. Boundary effects on single Q-boson spectrum are also studied. We illustrate these ...
