Chiral Perturbation Theory with an Isosinglet Scalar
Martin Hansen, Kasper Langæble, Francesco Sannino
We present an extension of chiral perturbation theory that explicitly includes an isosinglet scalar in the Lagrangian. The dynamical effects from the scalar state is of phenomenolo…
Extending Chiral Perturbation Theory with an Isosinglet Scalar
Martin Hansen, Kasper Langaeble, Francesco Sannino
We augment the chiral Lagrangian by an isosinglet scalar and compute the one-loop radiative corrections to the pion mass and decay constant, as well as the scalar mass. The calcula…
SIMP model at NNLO in chiral perturbation theory
Martin Hansen, Kasper Langaeble, Francesco Sannino
We investigate the phenomenological viability of a recently proposed class of composite dark matter models where the relic density is determined by 3 to 2 number-changing processes…
Morphology of High-Multiplicity Events in Heavy Ion Collisions
P. Naselsky, C. H. Christensen, P. R. Christensen +8
We discuss opportunities that may arise from subjecting high-multiplicity events in relativistic heavy ion collisions to an analysis similar to the one used in cosmology for the st…
