This paper presents the results of a comprehensive wide field search for transiting “ Hot Jupiter ” planets ( gas giant planets with an orbital period 1d \leq P \leq 16d ) in the globular cluster 47 Tucanae .
Motivated by the detection of the transit in HD209458 and the apparent lack of planetary detections in the core of 47 Tuc by Gilliland and coworkers , this work further addresses the question of giant planet frequency in 47 Tuc by observing , from the ground , a 52 ^ { \prime } \times 52 ^ { \prime } field centered on the cluster .
Hence this work is most sensitive to the uncrowded outer regions , where the stellar densities are significantly lower than the core , and concentrates on 21,920 main sequence stars within 2.5 magnitudes of the cluster turnoff ( and hence approaching solar in mass ) Our work comprises the largest ground-based transit search of a globular cluster to date , incorporating a 33-night time-series which allows us excellent sensitivity to detect Hot Jupiter planets .

Detailed Monte Carlo simulations incorporating the actual temporal sampling and photometric precision of the data predict that seven planets with an orbital period range of 1 - 16d should be present in our dataset , if 47 Tuc has the same planetary frequency observed in the solar neighbourhood .
A detailed search utilizing a matched filter algorithm , developed specifically for this project found no transit events .
This 3.3 \sigma result is consistent with the HST cluster core null detection of Gilliland and coworkers .
Our result indicates that system metallicity rather than crowding is the dominant effect inhibiting Hot Jupiter formation in this environment .
The 33-night dataset used for this result also led to the detection of 100 variable stars , including 69 new discoveries , which have been presented in a companion paper .
