HeavyFieldDimension

HeavyFieldDimension

is an option of SeriesEFT that determines whether heavy fields are counted by their canonical mass dimension or an extra suppression factor is included to account for the EFT counting when the heavy field is replaced in terms of light.

Details and Options

Examples

Basic Examples  (1)

Consider a heavy scalar ϕ:

By default the EFT order 2 is assigned to this heavy field (canonical mass dimension + EFT suppression factor when replacing ϕ by light fields: 1 + 1):

Only considering the canonical mass dimension can be achieved through:
