タイトル:
Open inflation and scalar suppression on large scales

アブストラクト:
Current CMB observations hint at there being a suppression
of scalar power on large scales. Focusing on two toy models,
we discuss how such a suppression may arise in the context
of open inflation models, in which inflation is preceded by false
vacuum decay. Whilst one source of suppression is the fast
rolling of the inflaton after the tunnelling event, we also see that
effects from the tunnelling itself must be taken into account.
