Late time behaviour of out-of-time-order correlator (OTOC) involving two generic non-conserved local operators shows an exponential decay in chaotic many body systems. However, it is recently observed that in random circuit models and also in certain holographic theories the OTOC involving U(1) conserved operator instead varies diffusively. In this talk I shall talk about the generalization of this by computing the late time behaviour of OTOC involving conserved operators corresponding to higher form symmetry. We start by discussing about 2-form fields and then generalize it for p-form fields in different spacetime dimensions. In all these cases we observe same diffusive late time behaviour of OTOC.
