  Placing D3 or anti-D3-branes at the tip of the Klebanov-Strassler background
results in uplifting the baryonic branch of the moduli space of the dual field
theory. In this paper we derive a mass formula for the scalar particle
associated with the motion along the baryonic branch, from both open and closed
string points of view. We show that both methods give the same mass at linear
order in number of (anti)D3-branes, thus providing a comprehensive check for
the recently found linearized supergravity solution describing backreacting
anti-D3-branes at the tip.
