# Action of a superfield?

Consider the superfield phi in two dimensions
$\phi\left( x,\theta \right) = A\left(x\right) + i \bar{\theta} \psi\left(x\right) + \frac{i}{2}\bar{\theta}\theta F\left(x\right)$
where the dimension of phi and A is zero (scalar field), the dimension of F is 1 (auxiliary field), the dimension of psi and theta is 1/2 (spinorial field).
The spinor theta has two real component (majorana condition): theta1 and theta2.
Which is the action for this superfield?
The mass term is $\int d^2 x d\theta_1 d\theta_2 m \phi^{2}$
The cubic interaction term is $\int d^2 x d\theta_1 d\theta_2 \lambda \phi^3$
And the kinetic term?
