Fundamental and composite scalars from extra dimensions

Alfredo Aranda, J. L. Diaz-Cruz, J. Hernandez-Sanchez +1

We discuss a scenario consisting of an effective 4D theory containing fundamental and composite fields. The strong dynamics sector responsible for the compositeness is assumed to b…

Noncommutative spaces, the quantum of time and the Lorentz symmetry

Juan M. Romero, J. D. Vergara, J. A. Santiago

We introduce three space-times that are discrete in time and compatible with the Lorentz symmetry. We show that these spaces are no commutative, with commutation relations similar…

The one-loop elastic coefficients for the Helfrich membrane in higher dimensions

J. A. Santiago, A. Zamora

Using a covariant geometric approach we obtain the effective bending couplings for a 2-dimensional rigid membrane embedded into a -dimensional Euclidean space. The Hamiltoni…
