Towards the renormalisation of the Standard Model effective field theory to dimension eight: Bosonic interactions II Das Bakshi, Supratim Rodríguez Chala, Mikael Díaz Carmona, Álvaro Guedes, Guilherme SMEFT Renormalisation BSM Positivity bounds RGE Data Availibility Statement This manuscript has associated data in a data repository. [Authors’ comment: The datasets generated during the current study are available in the Github repository https://github.com/SMEFT-Dimension8-RGEs.] We calculate the renormalisation group running of the bosonic Standard Model (SM) effective operators at one loop and to order v4/Λ4, with v∼246 GeV being the electroweak scale and Λ the unknown new physics threshold. We focus on contributions driven by one dimension-eight term and SM couplings, thus extending (and completing) the effort initiated in Chala et al. (SciPost Phys 11:065, 2021). arXiv:2106.05291, in which quantum corrections from pairs of dimension-six interactions were considered. We highlight some interesting consequences, including the renormalisation of loop-induced interactions by tree-level generated terms and, more importantly, the validity of positivity bounds on different operators inducing anomalous gauge quartic couplings. 2022-09-12T07:59:01Z 2022-09-12T07:59:01Z 2022-08-27 info:eu-repo/semantics/article Das Bakshi, S., Chala, M., Díaz-Carmona, A. et al.
