The difference of maximum and minimum bounds on the anomalous couplings, ($\\delta\\Delta\\kappa_{\\gamma}$, $\\delta\\lambda_{\\gamma}$) and ($\\delta\\Delta\\kappa_{Z}$, $\\delta\\lambda_{Z}$) are obtained as ($0.990$, $0.122$) and ($0.362$, $0.012$) without electron beam polarization at the beam energy of $E_{e}=140$ GeV for an integrated luminosity of $L_{int}=100$ fb$^{-1}$, respectively. With the possibility of $e-$beam polarization, we obtain more improved results as ($0.975$, $0.118$) and ($0.285$, $0.009$) for ($\\delta\\Delta\\kappa_{\\gamma}, \\delta\\lambda_{\\gamma}$) and ($\\delta\\Delta\\kappa_{Z}, \\delta\\lambda_{Z}$), respectively. The results are found to be comparable with the current experimental limits obtained from two-parameter analysis at the lepton and hadron colliders. It is found that the limits on the anomalous couplings ($\\Delta\\kappa_{Z}$, $\\lambda_{Z}$) through the process $ep\\to\\nu_{e}qZX$ at the LHeC can further improve the current experimental limits.", "revisions": [ { "version": "v1", "updated": "2014-06-30T12:28:33.000Z" } ], "analyses": { "keywords": [ "current experimental limits", "anomalous couplings", "electron beam energy", "electron beam polarization", "minimum bounds" ], "tags": [ "journal article" ], "publication": { "doi": "10.5506/APhysPolB.45.1947", "journal": "Acta Physica Polonica B", "year": 2014, "volume": 45, "number": 10, "pages": 1947 }, "note": { "typesetting": "TeX", "pages": 18, "language": "en", "license": "arXiv", "status": "editable", "inspire": 1303918, "adsabs": "2014AcPPB..45.1947C" } } }
