Analysis of excited neutrinos at the CLIC

Abstract

We analyze the single and pair production of excited neutrinos at the CLIC through the processes e + e − → ν * ν , e + e − → e + γ * e − → e + ν * W − , and e + e − → e + γ * γ * e − → e + ν * ν * e − (γ * is the Weizsacker-Williams photon). We examine comprehensively the excited neutrino signal and corresponding backgrounds to obtain limits on excited neutrino mass for various values of the integrated luminosity and center-of-mass energy. We show that the obtained bounds are more restricted than current experimental bounds. * mkoksal@cumhuriyet.edu.tr

A STUDY ON THE SEARCH POTENTIAL OF DOUBLY CHARGED LEPTONS AT THE SppC BASED ep COLLIDERS

“…Spin and isospin-1/2 excited fermions are considered as lowest radial and orbital excited states. Excited leptons with weak isospin states IW = 0 (singlet) and IW =1/2 (doublet) are studied widely in the literature [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25].…”

Excited Neutrino Search Potential of the FCC-Based Electron-Hadron Colliders

“…For the excited electron [11,12], muon [13], and neutrino [14][15][16][17], there are some phenomenological studies at the future high-energy colliders.…”
