On the breakdown of the perturbative interaction picture in big crunch/big bang or the true reason why perturbative string amplitudes on temporal orbifolds diverge

HIGHLIGHTS

• who: Igor Pesando from the Dipartimento di Fisica, Universitu00e0 di Torino and INF.N.-sezione di Torino, Via P. Giuria, Torino, Italy have published the paper: On the breakdown of the perturbative interaction picture in Big Crunch/Big Bang or the true reason why perturbative string amplitudes on temporal orbifolds diverge, in the Journal: Eur. Phys. J. C
• what: The authors discuss how the perturbative pArticle paradigm fails in certain background with space-like singularity but asymptotically flat which should admit a Smatrix. The answer as the authors show is affirmative. Instead of the analysis . . .
