The influence of LHCB hadronic calorimeter nuclear length on the trigger efficiency $\epsilon $ for $pp \rightarrow (B_d^0 \rightarrow \pi^+ \pi^-) + X$ has been investigated. The dependences of $\epsilon $ on the transverse energy $E_t $ of two most energetic event particles have been obtained. The influence of electronics noise and precluster isolation parameter on $\epsilon $ has been investigated. Registration efficiency of minimum bias and pile-up events as $B_d^0 $-event candidates has been investigated too.
