Title: | Search for heavy Majorana neutrinos in same-sign dilepton channels in proton-proton collisions at root s = TeV | Authors: | Karapınar, Güler CMS Collaboration |
Keywords: | Beyond Standard Model Hadron-Hadron scattering (experiments) |
Publisher: | Springer | Abstract: | A search is performed for a heavy Majorana neutrino (N), produced in leptonic decay of a W boson propagator and decaying into a W boson and a lepton, with the CMS detector at the LHC. The signature used in this search consists of two same-sign leptons, in any flavor combination of electrons and muons, and at least one jet. The data were collected during 2016 in proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 35.9 fb(-1). The results are found to be consistent with the expected standard model background. Upper limits are set in the mass range between 20 and 1600 GeV in the context of a Type-I seesaw mechanism, on |V-eN|(2), |V-N|(2), and |VeNV *|(2)/(|V-eN|(2)+|V-N|(2)), where V-N is the matrix element describing the mixing of N with the standard model neutrino of flavor = e, . For N masses between 20 and 1600 GeV, the upper limits on |V-N|(2) range between 2.3 x 10(-5) and unity. These are the most restrictive direct limits for heavy Majorana neutrino masses above 430 GeV. | URI: | https://doi.org/10.1007/JHEP01(2019)122 https://hdl.handle.net/11147/8586 |
