Abstract
Using a geometric description of 2HDM, the -odd invariants are classified into three independent sectors: scalar potential, Yukawa interaction, and CKM matrix. We calculate the effective thermal potential of 2HDM in a basis invariant way and show that the phases in the CKM matrix cannot leak to the effective potential at all orders. In the 2HDM with a softly broken symmetry, the leading thermal correction to the effective potential tends to restore the symmetry at high temperatures.
