Study on the anomalous quartic W+W− γγ couplings of electroweak bosons in e− p collisions at the LHeC and the FCC-he
Abstract
In this paper, a study is carried out on the e− p →
e−
γ
∗ p → pW−
γνe production to probe quarticW+W−
γγ
c√ouplings at the LargeHadron electron Collider (LHeC)with
s = 1.30, 1.98 TeV and at the Future Circular Colliderhadron
electron (FCC-he) with
√
s = 3.46, 5.29 TeV. Production
cross-sections are determined for both at leptonic and
hadronic decay channels of the W-boson.With the data from
future e− p colliders, it is possible to obtain sensitivity measures
at 95% C.L. on the anomalous fM,i/ 4 and fT, j/ 4
couplings which are competitive with the limits obtained by
the LHC, as well as with others limits reported in the literature.
The production mode e− p → e−
γ
∗ p → pW−
γνe
in e− p collisions offers a window for study the quartic
W+W−
γγ electroweak bosons couplings at the LHeC and
the FCC-he, which provides a much cleaner collision environment
than the LHC.
