T-Duality Considerations for Hadronic Strings
Physics Review D
We show that a simple account of hadronic high energy total cross sections and of the observed masses and flavor-gauge-like couplings of the familiar vector mesons is obtained in a hadronic string model suggested by QCD in the limit of a large number of colors. Our picture involves a Minkowski space which, in addition to the well-established continuous one time and three space dimensions, is endowed with an extra discrete space dimension involving a minimal two-point lattice with a spacing of order 10−14 cm in one of the two T-dual pictures. New mesonic states with characteristic decay modes are expected in such a picture.
