Particle-dimer approach for the Roper resonance in a finite volume
Daniel Severt, Maxim Mai, Ulf-G. Meißner
We propose a new finite-volume approach which implements two- and three-body dynamics in a transparent way based on an Effective Field Theory Lagrangian. The formalism utilizes a p…
Towards the finite-volume spectrum of the Roper resonance
Daniel Severt
The finite-volume energy levels corresponding to the Roper resonance based on a two-flavor chiral effective Lagrangian at leading one-loop order are investigated. It is shown that…
Electric dipole moments of baryons with bottom quarks
Y. Ünal, D. Severt, J. de Vries +2
Triggered by experimental prospects to measure electromagnetic dipole moments of baryons containing a bottom quark, we calculate the CP-odd electric dipole moments (EDMs) of spin-1…
The Roper Resonance in a finite volume
Daniel Severt, Ulf-G. Meißner
We calculate the energy levels corresponding to the Roper resonance based on a two-flavor chiral effective Lagrangian for pions, nucleons, deltas and the Roper resonance at leading…
Flavor decomposition of the pion-nucleon -term
Daniel Severt, Ulf-G. Meißner, Jambul Gegelia
We re-analyze the flavor decomposition of the pion-nucleon -term in the framework of baryon chiral perturbation to fourth order. We employ a covariant and the heavy baryon frame…
