Some Properties of Charge-Conjugated Spinors in dimensions
Spinors for an arbitrary Minkowski space with signature (, ) are
reassessed in connection with -dimensional free Dirac action. The
possibility of writing down kinetic and mass terms for charge-conjugated
spinors is discussed in terms of the number of time-like directions of the
space-time.Comment: 6 pages (latex
Cuscuton kinks and branes
In this paper, we study a peculiar model for the scalar field. We add the
cuscuton term in a standard model and investigate how this inclusion modifies
the usual behavior of kinks. We find the first order equations and calculate
the energy density and the total energy of the system. Also, we investigate the
linear stability of the model, which is governed by a Sturm-Liouville
eigenvalue equation that can be transformed in an equation of the Shcr\"odinger
type. The model is also investigated in the braneworld scenario, where a first
order formalism is also obtained and the linear stability is investigated.Comment: 21 pages, 9 figures; content added; to appear in NP
