Sudakov Representation of the Cachazo-He-Yuan Scattering Equations Formalism
Grigorios Chachamis, Diego Medrano Jiménez, Agustín Sabio Vera +1
We show that the use of Sudakov variables greatly simplifies the study of the solutions to the scattering equations in the Cachazo-He-Yuan formalism. We work in the center-of-mass…
Projectivity of Planar Zeros in Field and String Theory Amplitudes
Diego Medrano Jimenez, Agustin Sabio Vera, Miguel A. Vazquez-Mozo
We study the projective properties of planar zeros of tree-level scattering amplitudes in various theories. Whereas for pure scalar field theories we find that the planar zeros of…
Planar Zeros in Gauge Theories and Gravity
Diego Medrano Jimenez, Agustin Sabio Vera, Miguel A. Vazquez-Mozo
Planar zeros are studied in the context of the five-point scattering amplitude for gauge bosons and gravitons. In the case of gauge theories, it is found that planar zeros are dete…
One-parameter isospectral special functions
M. A. Reyes, D. Jimenez, H. C. Rosu
Using a combination of the ladder operators of Pina [Rev. Mex. Fis. 41 (1995) 913] and the parametric operators of Mielnik [J. Math. Phys. 25 (1984) 3387] we introduce second order…
Second-order linear differential equations associated to a Riccati equation of constant coefficients
H. C. Rosu, O. Cornejo, M. Reyes +1
We present several second-order linear differential equations that are associated to a particular Riccati equation with only one constant parameter in its coefficients through the…
Linear second-order differential equations for barotropic FRW cosmologies
H. C. Rosu, O. Cornejo, M. Reyes +1
Simple linear second-order differential equations have been written down for FRW cosmologies with barotropic fluids by Faraoni. His results have been extended by Rosu, who employed…
