“…The final neutrino (that we know of), the tau neutrino, was not discovered until 2000, by the DONUT collaboration [10]. The ν τ was produced from decays of particles produced in a fixed-target experiment with 800 GeV protons from the Fermilab…”

T2K (Tokai to Kamioka) is a long baseline neutrino experiment with the primary goal of measuring the neutrino mixing angle θ 13 . It uses a muon neutrino beam, produced at the J-PARC accelerator facility in Tokai, sent through a near detector complex on its way to the far detector, Super-Kamiokande. Appearance of electron neutrinos at the far detector due to oscillation is used to measure the value of θ 13 .

“…Before concluding this section, we should mention that independent limits could also be derived from the DONUT experiment, through an analysis similar to the one presented in [50] that yielded limits on the ν τ magnetic moment. We have estimated that the constraints from DONUT would be at least one order of magnitude worse than the limits obtained from LEP; however, it should be remarked that these limits would be inferred directly from the absence of anomalous interactions for a neutrino beam with an identified ν τ component [51].…”

Abstract.A Majorana neutrino is characterized by just one flavor diagonal electromagnetic form factor: the anapole moment, that in the static limit corresponds to the axial vector charge radius r 2 A . As is the case for the vector charge radius of a Dirac neutrino, proving that this quantity is a well defined physical quantity is non trivial. I will first describe briefly the origin of the long standing controversy about the physical or non physical nature of the neutrino charge radius. Then I will argue that, in contrast to Dirac neutrino electromagnetic form factors, for Majorana neutrinos cosmological and astrophysical arguments do not provide useful informations on r 2 A . Therefore this quantity has to be studied by means of terrestrial experiment. Finally, I will discuss the constraints that can be derived on r 2 A for the tau neutrino from a comprehensive analysis of the data on single photon production off Z-resonance, and I will conclude with a few comments on ν µ scattering data from the NuTeV, E734, CCFR and CHARM-II collaborations and on the limits implied for r 2 A for the muon neutrino.

“…Since this time it has achieved remarkable success with the discovery, as predicted by the model of the tau lepton [1] along with the charm [2,3] and bottom quarks [4] in the 1970s, the W and Z bosons in the 1980s [5][6][7], the top quark in the 1990s [8] and the tau neutrino in 2000 [9]. The final particle in the standard model, the Higgs boson was discovered at CERN in July 2012 [10,11], completing the set of particles predicted by the SM.…”

In this thesis I study the collider phenomenology of BSM physics at the LHC, concentrating on the Higgs boson and supersymmetery. The implications and effects on cross sections of the loss of unitarity in scattering processes involving multiple vector bosons and/or the Higgs, when the Higgs couplings to the W and the Z are non-SM, is studied using an effective Lagrangian. Subsequently methods to remove unwanted background from transversely polarised vector bosons are explored, which enable an estimation of the potential to measure the Higgs couplings to weak bosons in a model-independent way via vector boson fusion. MSSM effects on Higgs production and decay are also considered, concentrating on the effects due to light stops, sbottoms and staus. Amongst other things, we find that light 3 rd generation squarks generally produce asymmetrical alteration in signal strengths of different production channels, generally causing µ V BF µ ggF > 1. Finally we extend some ATLAS analyses in the low ∆m = mt − mχ0 1 region, extending the excluded masses of light stops. This enables us to limit the maximum effects of light stops on the Higgs, and further limits the parameter space where the light stop scenario of electroweak baryogenesis is viable.
