The search for di-Higgs production at the LHC in order to set limits on the Higgs trilinear coupling and constraints on new physics is one of the main motivations for the LHC high-luminosity phase. Recent experimental analyses suggest that such analyses will only be successful if information from a range of channels is included. We therefore investigate di-Higgs production in association with two hadronic jets and give a detailed discussion of both the gluonand the weak boson-fusion (WBF) contributions, with a particular emphasis on the phenomenology with modified Higgs trilinear and quartic gauge couplings. We perform a detailed investigation of the full hadronic final state and find that hh j j production should add sensitivity to a di-Higgs search combination at the HL-LHC with 3 ab −1 . Since the WBF and GF contributions are sensitive to different sources of physics beyond the Standard Model, we devise search strategies to disentangle and isolate these production modes. While gluon fusion remains non-negligible in WBF-type selections, sizeable new physics contributions to the latter can still be constrained. As an example of the latter point we investigate the sensitivity that can be obtained for a measurement of the quartic Higgs-gauge boson couplings.

“…[30]. In our previous work [19,31], we addressed the numerical instability originating from the small Gram determinant (det G) scalar 4-point integrals [18]. In order to solve this problem, we developed the LoopTools-2.8 package and checked the results with those by using OneLoop package [32] to verify the correctness of our codes.…”

We report on the precision predictions for the e + e − → Z Zγ process including Z -boson leptonic decays at the ILC in the standard model (SM). The calculation includes the full next-to-leading (NLO) electroweak (EW) corrections and high order initial state radiation (h.o. ISR) contributions. We find that the NLO EW corrections heavily suppress the LO cross section, and the h.o. ISR effects are notable near the threshold while become small in high energy region. We present the LO and the NLO EW+h.o. ISR corrected distributions of the transverse momenta of final Z -boson and photon as well as the Z -pair invariant mass, and we investigate the corresponding NLO EW and h.o. ISR relative corrections. We also study the leptonic decays of the final Z -boson pair by adopting the MadSpin method where the spin correlation effect is involved. We conclude that both the h.o. ISR effects and the NLO EW corrections are important in exploring the Z Zγ production at the ILC.

“…In the following we focus on effects from electroweak corrections. NLO Weak corrections to ttH production have been calculated in [22] with a semi-automatic approach and including also NLO QED effects in [23]. Afterwards, NLO EW (Weak+QED) corrections have been calculated in a completely automated approach in [24] for the ttH, ttZ, ttW + and ttW − processes, together with NLO QCD corrections.…”
