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…
Hidden strongly interacting massive particles
Matti Heikinheimo, Kasper Langaeble, Kimmo Tuominen
We consider dark matter as Strongly Interacting Massive Particles (SIMPs) in a hidden sector, thermally decoupled from the Standard Model heat bath. Due to its strong interactions,…
Phase structure of complete asymptotically free SU() theories with quarks and scalar quarks
Frederik F. Hansen, Tadeusz Janowski, Kasper Langaeble +4
We determine the phase diagram of complete asymptotically free SU() gauge theories featuring complex scalars and Dirac quarks transforming according to the fundame…
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…
