| contents | Non-decoupling effects of heavy scalars and vector fields play an important role in the indirect search of Beyond the Standard Model (BSM) physics at the LHC. By exploiting some new differential equations for the 1-PI amplitudes, we show that such non-decoupling effects are absent for quite a general class of effective field theories involving dimension six two-derivatives and dimension eight four-derivatives operators, once resummation in certain BSM couplings is taken into account and some particular regimes of the relevant couplings are considered. |
