Charge Quantization and the Standard Model from the $CP^{2}$ and $CP^{3}$ Nonlinear $σ$ -Models

Simeon Hellerman, John Kehayias, Tsutomu T. Yanagida

We investigate charge quantization in the Standard Model (SM) through a $CP^{2}$ nonlinear sigma model (NLSM), $S U (3)_{G} / (S U (2)_{H} \times U (1)_{H})$ , and a $CP^{3}$ model…

Charge Quantization in the $CP (1)$ Nonlinear Sigma-Model

Simeon Hellerman, John Kehayias, Tsutomu T. Yanagida

We investigate the consistency conditions for matter fields coupled to the four-dimensional ( $N = 1$ supersymmetric) $CP (1)$ nonlinear sigma model (the coset space…

Quantum Instability of the Emergent Universe

Anthony Aguirre, John Kehayias

We perform a semi-classical analysis of the Emergent Universe scenario for inflation. Fixing the background, and taking the inflaton to be homogenous, we cast the inflaton's evolut…
