A string theory which isn't about strings

I will talk on ​​ab initio quantized bosonic string theory with left-right asymmetric worldsheet vacuum. Remarkably, ​when ​quantized​ in​ this way, the string spectrum consists only of a finite number of degrees of freedom: string gravity (massless spin-two, Kalb-Ramond and dilaton fields) and two massive spin-two Fierz-Pauli fields. The massive spin-two fields have negative norm, opposite mass-squared, and provides a Lee-Wick type extension of string gravity. I present two further evidences that this string theory is a quantum field theory. Scattering amplitude of four dilatons is shown to be a rational function of kinematic invariants, ​which,​ in D=26​, ​factorizes into contributions of massless spin-two and a pair of massive spin-two fields. The string one​ ​loop partition function is shown to perfectly agree with one loop Feynman diagram of string gravity and two massive spin-two fields. In particular, it does not exhibit modular invariance.

ISC or Intellectually Stimulating Craic is a weekly seminar for Graduate and Undergraduate students that encourages the interdisciplinary exchange of ideas within the physics department. The rules are simple: 1. No physics. 2. The talk topic is classified until the last moment.
