Do We Live in the Swampland?

Understand

A low-energy effective theory is said to be in the swampland if it does not have any consistent UV completion inside a theory of quantum gravity.

• The natural question is if the standard model of particle physics, possibly with some minimal extensions, are in the swampland or not.
• We discuss this question in view of the recent swampland conjectures.
• We prove a no-go theorem concerning the modification of the Higgs sector.
