      "value": "We propose a renormalization scheme for non-local Quantum Field Theories (QFTs) with infinite derivatives inspired by string theory. Our Non-locality Renormalization Scheme (NRS) is inspired by Dimensional Regularization (DR) in local QFTs and is shown to significantly improve the UV behavior of non-local QFTs. We illustrate the scheme using simple examples from the  $$\\phi ^{3}$$  <math> <msup> <mi>\u03d5</mi> <mn>3</mn> </msup> </math>   and  $$\\phi ^{4}$$  <math> <msup> <mi>\u03d5</mi> <mn>4</mn> </msup> </math>   theories, then we evaluate the viability of NRS-enhanced non-local QFTs to solve the hierarchy problem using a simplified toy model. We find that non-locality protects the mass of a light scalar from receiving large corrections from any UV sector to which it couples, as long as the non-locality scale  $$\\Lambda $$  <math> <mi>\u039b</mi> </math>   is sufficiently smaller than the scale of the UV sector. We also find that NRS eliminates any large threshold corrections from the IR sector."
