abstract
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 from ultra-relativistic Carrollian limit of tensile strings. Due to the existence of this symmetry, the BMS$_3$ algebra of constraints, which is obtained as the Carrollian limit of two Virasoro algebras of the standard tensile strings, should be replaced with an BMS$_3$ algebra extended by a weight one operator. To establish further the existence and necessity of the Carroll-Weyl gauge symmetry, we carefully work through Hamiltonian analyses of constrained/gauged systems. We also discuss the extended BMS$_3$ algebra of constraints.

Null bosonic string quantization on Carrollian worldsheets requires an extra scalar ghost pair for Carroll-Weyl scaling, yielding a bcs system that alters the BRST complex and anomaly cancellation beyond the standard BMS bc treatment.
An overlooked local symmetry in the null string action reduces physical degrees of freedom to D-3 rather than the D-2 reported in prior literature.
