This protocluster is characterized by both the large overdensity of spectroscopically confirmed members, $\\delta_{gal}=10.5\\pm2.8$, and a significant overdensity in photometric redshift members. The halo mass of this protocluster is estimated, by a variety of methods, to be roughly $3\\times10^{14}$ $\\mathcal{M}_{\\odot}$ at $z\\sim3","authors_text":"A. Cimatti, A. Durkalec, A. Fontana, A.
