Abstract: I discuss some universal properties associated with p-wave resonance and derive a set of exact relations analogous to the s-wave resonance. However, in contrary to the s-wave case, the effective range R is crucial for a consistent theoretical formulation. As a result, one obtains two set of adiabatic relations, one associated with scattering volume v and the other R. Experimental evidences for the existence of these two contacts via radio-frequency spectroscopy is presented and a measurement of energetics close to p-wave resonance is accomplished using the adiabatic theorems. Dynamical growth of contacts is monitored and is related to the population of closed channel p-wave dimers. I conclude by discussing some remaining theoretical problems that are still worth investigating.
