Query: An Attempt to Study Pentaquark Baryons in String Theory   An attempt to study recently observed Pentaquark baryons is performed in the
dual string theory of QCD. Mass formulae for Pentaquark baryons are naively
estimated in the Maldacena's prototype model for supersymmetric QCD and a more
realistic model for the ordinary QCD.
