Confusion About Complex and Scalar Fields
https://physics.stackexchange.
The value of the complex-valued field at a point is a complex-valued function over the phase space (the space of solutions to the eom). Hence it ...

1 Quantizing the Complex Scalar Field. We will analyze the QFT of a (free) complex scalar. The Lagrangian of this system is. L = (∂µφ.
Quantum Field Theory I

The symmetry group for the complex scalar is simply U(1). The above discussions only applied to operators, let us finally discuss transformations for states.
Scalar field theory
https://en.wikipedia.org
A scalar field is invariant under any Lorentz transformation. The only fundamental scalar quantum field that has been observed in nature is the Higgs field.
