# M-Strings

@article{Haghighat2013MStrings, title={M-Strings}, author={Babak Haghighat and Amer Iqbal and Can Kozçaz and Guglielmo Lockhart and Cumrun Vafa}, journal={Communications in Mathematical Physics}, year={2013}, volume={334}, pages={779-842} }

M2 branes suspended between adjacent parallel M5 branes lead to light strings, the ‘M-strings’. In this paper we compute the elliptic genus of M-strings, twisted by maximally allowed symmetries that preserve 2d (2, 0) supersymmetry. In a codimension one subspace of parameters this reduces to the elliptic genus of the (4, 4) supersymmetric An-1 quiver theory in 2d. We contrast the elliptic genus of N M-strings with the (4, 4) sigma model on the N-fold symmetric product of $${{\mathbb{R}}^4}$$R4…
