Here it is. "New" Official Dragon Ball manga titled Dragon Ball SD(presumably SD stands for Super Deformed) by Naho Ooishi with supervision by Akira Toriyama. It's a spin off series made for a new Shueisha magazine Saikyô Jump(Which i assume translates to Strongest Jump , my knowledge of japanese is quite limited).
Note that this is not a continuation of the Dragon Ball story but a spin-off meant mainly for children.
