We study new supergravity solutions related to large- N ~( c ) $ mathcal{N} = 1 $ supersymmetric gauge field theories with a large number N ~( f )of massive flavors. We use a recently proposed framework based on configurations with N ~( c )color D5 branes and a distribution of N ~( f )flavor D5 branes, governed by a function N ~( f ) S ( r ). Although the system admits many solutions, under plausible physical assumptions the relevant solution is uniquely determined for each value of x ?≡? N ~( f )/ N ~( c ). In the IR region, the solution smoothly approaches the deformed Maldacena-Nú?ez solution. In the UV region it approaches a linear dilaton solution. For x ??2 describe a “Seiberg dual” picture where N ~( f )???2 N ~( c )flips sign.
