Massive conformal particles with non-Abelian charges from free U(2N,2N)-twistor dynamics: quantization and coherent states
M. Calixto
The inclusion of non-Abelian U(N) internal charges (other than the electric charge) into Twistor Theory is accomplished through the concept of "colored twistors" (ctwistors for sho…
Symmetry group of massive Yang-Mills theories without Higgs and their quantization
V. Aldaya, M. Calixto, F. F. López-Ruiz
We analyze the symmetry group of massive Yang-Mills theories and their quantization strongly motivated by an already proposed alternative to the Standard Model of electroweak inter…
Non-Canonical Perturbation Theory of Non-Linear Sigma Models
V. Aldaya, M. Calixto, F. F. López-Ruiz
We explore the O(N)-invariant Non-Linear Sigma Model (NLSM) in a different perturbative regime from the usual relativistic-free-field one, by using non-canonical basic commutation…
Conformal Spinning Quantum Particles in Complex Minkowski Space as Constrained Nonlinear Sigma Models in U(2,2) and Born's Reciprocity
M. Calixto, E. Pérez-Romero
We revise the use of 8-dimensional conformal, complex (Cartan) domains as a base for the construction of conformally invariant quantum (field) theory, either as phase or configurat…
A Quantizable Model of Massive Gauge Vector Bosons without Higgs
V. Aldaya, M. Calixto, F. F. Lopez-Ruiz
We incorporate the parameters of the gauge group G into the gauge theory of interactions through a non-linear partial-trace sigma-model Lagrangian on G/H. The minimal coupling of t…
Thermal Vacuum Radiation in Spontaneously Broken Second-Quantized Theories on Curved Phase Spaces of Constant Curvature
M. Calixto, V. Aldaya
We construct second-quantized (field) theories on coset spaces of pseudo-unitary groups U(p,q)$. The existence of degenerated quantum vacua (coherent states of zero modes) leads to…
