Poster title: Unveiling the RR Lyrae population of bulge globular clusters

Poster abstract: Significant observational efforts have been carried out in the last decades to 
characterize the bulge globular clusters (GC). However, the strong field contamination, extinction, 
and crowding still severely hampers the investigation of these targets. Particularly, the RR Lyrae  
population in metal-poor GC ([Fe/H <~ -1.0]) is crucial to provide accurate distances and to constrain 
the helium abundances. In this context, we present the early results of an ongoing survey aimed at 
unveiling the missing RR Lyrae population in the core regions of  metal-poor bulge GCs, by making 
use of AO-assisted photometry obtained with SAM@SOAR telescope. Light curves of hundreds of 
prospect stars  in two such targets (HP1 and NGC6723) were built and the new RR Lyrae 
candidates identified. Their spatial distribution and properties will be presented, thus providing 
important constraints to study these GCs.
