Null Strings Gauged and Reloaded, II: Consistent Classical Treatment of the Null Strings
M. M. Sheikh-Jabbari, H. Yavartanoo
We observed that the null strings, tensionless strings with Carrollian worldsheets, exhibit an extra gauge symmetry, \textit{Carroll-Weyl} gauge symmetry, which cannot be obtained…

Null Strings Gauged and Reloaded, I: Null Strings Have Carroll-Weyl Gauge Symmetry
M. M. Sheikh-Jabbari, H. Yavartanoo
Null strings, strings with Carrollian worldsheets, are traditionally described by the Isberg-Lindström-Sundborg-Theodoridis (ILST) action, which is obtained via a tensionless limit…
