Sphaleron without shape mode and its oscillon
K. Oles, J. Queiruga, T. Romanczukiewicz +1
We find that an oscillon can possess a characteristic double oscillation structure even though it results in a decay of a sphaleron which does not have any positive energy vibratio…
Semi-BPS sphaleron and its dynamics
A. Alonso-Izquierdo, S. Navarro-Obregón, K. Oles +3
We construct a simple field theory in which a sphaleron, i.e., a saddle-point particle-like solution, forms a semi-BPS state with a background defect that is an impurity. This mean…
Inclusion of radiation in the CCM approach of the model
S. Navarro-Obregón, L. M. Nieto, J. M. Queiruga
We present an effective Lagrangian for the model that includes radiation modes as collective coordinates. The coupling between these modes to the discrete part of the spectru…
