The discovery of 125 GeV boson and its properties corroborate that the Standard Model (SM) is the correct effective theory at around weak scale. While the SM is pretty successful describing nature at around electroweak scale, it however has several glaring shortcomings where Beyond the SM (BSM) physics or New physics (NP) is required. Several experiments are currently ongoing to find direct and indirect evidences of BSM physics however, all are yet to find any clear evidence it. In this talk I will discuss about possible signatures of sub-TeV weakly coupled resonances at the Large Hadron collider and, flavor machine such as LHCb and Belle-II.
