Isotropy of the Speed of Light
Diego J. Castano, Lawrence C. Hawkins
It is shown theoretically that the speed of light cannot depend on direction.
Conicoid Mirrors
Diego J. Castano, Lawrence Hawkins
The first order equation relating object and image location for a mirror of arbitrary conic-sectional shape is derived. It is also shown that the parabolic reflecting surface is th…
Constraints on the Minimal Supergravity Model with Large
Howard Baer, Michal Brhlik, Diego Castano +1
In the minimal supergravity model (mSUGRA), as the parameter increases, the charged Higgs boson and light bottom squark masses decrease, which can potentially increase cont…
Naturalness Lowers the Upper Bound on the Lightest Higgs Boson Mass in Supersymmetry
Greg Anderson, Diego Castano, Antonio Riotto
We quantify the extent to which naturalness is lost as experimental lower bounds on the Higgs boson mass increase, and we compute the natural upper bound on the lightest supersymme…
Consequences of Supergravity with Gauged Symmetry
Diego J. Castano, Daniel Z. Freedman, Cristina Manuel
The structure of gauged R supergravity Lagrangians is reviewed, and we consider models with a hidden sector plus light fields of the MSSM. A simple potential for the hidden sector…
Naturalness and superpartner masses or when to give up on weak scale supersymmetry
Greg Anderson, Diego Castano
Superpartner masses cannot be arbitrarily heavy if supersymmetric extensions of the standard model explain the stability of the gauge hierarchy. This ancient and hallowed motivatio…
Measures of fine tuning
Greg Anderson, Diego Castano
Fine-tuning criteria are frequently used to place upper limits on the masses of superpartners in supersymmetric extensions of the standard model. However, commonly used prescriptio…
Discrete symmetries and isosinglet quarks in low-energy supersymmetry
Diego J. Castano, Stephen P. Martin
Many extensions of the minimal supersymmetric standard model contain superfields for quarks which are singlets under weak isospin with electric charge -1/3. We explore the possibil…
Renormalization Group Study of the Standard Model and its Extensions: II. the Minimal Supersymmetric Standard Model
D. J. Castano, E. J. Piard, P. Ramond
In this paper we summarize the minimal supersymmetric standard model as well as the renormalization group equations of its parameters. We proceed to examine the feasability of the…
Mass and mixing angle patterns in the Standard Model and its Minimal Supersymmetric Extension
H. Arason, D. J. Castano, E. J. Piard +1
Using renormalization group techniques, we examine several interesting relations among masses and mixing angles of quarks and leptons in the Standard Model. We extend the analysis…
