LSZ ghostbusters in the quadratic gravity stage
O. P. Santillán
The present letter considers the quantization method developed in [1]-[9], which postulates that, in several situations, negative norm or ghost states can be avoided in order to gi…

Gauge preservation in renormalization for Yang-Mills and gravity theories
Osvaldo Santillán, Alejandro Morano
In the present work, multiplicative renormalization \cite{dixon} for Yang-Mills theories is reviewed. While this subject is not new, it is suggested that a clear understanding of t…

About gravitational radiation of semi local strings with non compact internal modes
A. Morano, O. Santillán
The present work studies the gravitational radiation of a non abelian vortex with a non compact internal moduli describing its excitations. This situation may be realised by semi-l…
