|Title:||Phenomenology of the anomaly `free' general U(1) extended Standard Model|

The general $U(1)$ extension of the Standard Model is an interesting scenario where we have the three generations of the right handed neutrinos.
In this scenario an additional scalar is also added in the model which induces the Majorana mass term of the right handed neutrinos after the symmetry breaking.
Such a model is specially interesting due to the presence of a neutral gauge boson, $Z^\prime$, which has a very rich phenomenology.
The interaction between the $Z^\prime$ and the other particles are governed by the existence of the general $U(1)$ charges after the anomaly cancellation.
In this talk we will discuss a variety of such phenomenologies, for example neutrino mass, Higgs production from the $Z^\prime$ at the colliders.
It is interesting to mention that such models can also contain the dark matter candidates maintaining the minimality of the particle content.
The constraints on the relevant model parameters have been calculated using the constraints obtained from the Large Hadron Collide at the Run-2.
