Sphaleron without shape mode and its oscillon
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 discrete vibrational mode (shape mode). We show that dynamics of such an oscillon can still be qualitatively captured by collect...
