Consider the superfield phi in two dimensions(adsbygoogle = window.adsbygoogle || []).push({});

[itex] \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) [/itex]

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 [itex] \int d^2 x d\theta_1 d\theta_2 m \phi^{2}[/itex]

The cubic interaction term is [itex] \int d^2 x d\theta_1 d\theta_2 \lambda \phi^3[/itex]

And the kinetic term?

Please help me!
