BSM physics Boosted object searches at ATLAS and CMS

Several models of physics Beyond the Standard Model predict new heavy particles that can decay to boosted W,Z,H bosons or top quarks, that is, with a transverse momentum that considerably exceeds their rest mass. This is a new kinematic regime where classical reconstruction approach relying on one-to-one jet to parton assignment is not adequate anymore. New techniques for the reconstruction of such objects at the LHC have been recently developed and succesfully applied to analyses based on the Run I data at 8\,TeV allowing to significanlty extend the sensitivity of BSM searches. These new reconstruction approaches are now even more crucial for the incoming Run II at 13\,TeV.
