Abstract
The Groningen LHCb group is preparing to obtain the first measurement of the decay $B_c\rightarrow \tau\nu_{\tau}$ during the next data taking period of the Large Hadron Collider (LHC) at CERN. With a full detector output at a rate of 30Mhz, decisions to save or discard data must be made in real time while ensuring the recorded data is sufficient for performing offline analysis later on. The following thesis therefore will focus on the validation of software (called a trigger-line) written to identify the desired decay and trigger the LHCb detector to save relevant events for future analysis. Utilising the recently upgraded LHCb detector, the $B_c\rightarrow \tau\nu_{\tau}$ trigger-line has shown to efficiently reject background candidates when tested on simulated data sets. The results of this thesis provide sufficient evidence that the $B_c\rightarrow \tau\nu_{\tau}$ trigger is ready for implementation in the upcoming data collection period.
