A relation between massive and massless string tree amplitudes
Sitender Pratap Kashyap, Carlos R. Mafra, Mritunjay Verma +1
We uncover a relation between the scattering amplitudes of massive strings and the expansion of the massless string amplitude at tree level. More precisely, the n-point tree a…

One Loop Mass Renormalization of Massive States Using Pure Spinor Formalism
Sitender Pratap Kashyap, Mritunjay Verma
As a check of the first massive integrated vertex operator in the pure spinor formalism constructed in arXiv:1802.04486, we compute the one loop 2-point function of the stable non-…
