Higgs self interaction
Web29 de mar. de 2024 · The allowed range for the Higgs self-coupling is shown by the intersection of the observed limit with the theoretical prediction, between -1.5 and 6.7 times the Standard Model prediction. Physicists were able to set a limit on the HH production cross section of 4.1 times the Standard Model prediction. WebWe calculate the two-loop contributions from a modified trilinear Higgs self-interaction, , to the electroweak oblique parameters and . Using the current bounds on and from electroweak measurements, we find the 95% …

WebInstead, to obtain additional insight, we take one step back from this and will address the question of “how” the Gravitino and Goldstino obtain these self-couplings. This approach is strongly analogous to that of the Higgs mechanism presented by Englert and Brout [] (see also an excellent review of these topics []).In this approach we start from a classical … Web5 de jun. de 2012 · The contributions from the Higgs self-interaction which are negligible for the running of the top- Yukawa and the strong coupling but important for the running of the Higgs self-coupling are also evaluated.
