The Standard Model of particle physics assumes that the world consists of leptons (electrons, muons, taus and neutrinos) and quarks that are elementary particles. We measure that leptons and quarks have a mass hierarchy that could be explained by an underlying substructure of even smaller particles. Then leptons and quarks would be the lowest stable energetic states and higher energy excited states would exist and could be probed experimentally. In this thesis a search for these excited states… 

Reflecting on Higgs: Spin and parity measurement in the H → WW → eνeμνμ channel

To test if the discovered particle in 2012 at LHC’s ATLAS and CMS experiments is indeed a Standard Model (SM) Higgs boson, its spin and CP quantum numbers have to be measured. A SM Higgs boson should

Heavy and excited leptons in the OPAL detector

This M.Sc. thesis describes a search for exotic leptons. The search has been performed using data from the OPAL detector at the Large Electron Positron collider at CERN. The total integrated

Excited-quark and -lepton production at hadron colliders.

Production rates and signatures are discussed for hadron colliders presently operating or under study and large lepton yields are expected if quarks and leptons share common subconstituents.

The LHC resumed operation in February 2011, colliding proton beams at a center of mass energy of 7 TeV. The first challenge consisted of understanding the detector performance with increasing

A search for an excited muon decaying to a muon and two jets in $pp$ collisions at $\sqrt{s}$ = 8 TeV with the ATLAS detector

A new search signature for excited leptons is explored. Excited muons are sought in the channel pp → µµ ∗ → µµ jet jet, assuming both the production and decay occur via a contact interaction. The

Seesaw neutrino signals at the Large Hadron Collider

We discuss the scenario with gauge singlet fermions (right-handed neutrinos) accessible at the energy of the Large Hadron Collider. The singlet fermions generate tiny neutrino masses via the seesaw

New Tests for Quark and Lepton Substructure

If quarks and leptons are composite at the energy scale ..lambda.., the strong forces binding their constituents induce flavor-diagonal contact interactions, which have significant effects at

New parton distributions for collider physics

We extract new parton distribution functions (PDFs) of the proton by global analysis of hard scattering data in the general-mass framework of perturbative quantum chromodynamics. Our analysis

Higgs triplets in the standard model.

The phenomenology of a Higgs sector for the standard model which contains both doublet and triplet fields (under SU(2){sub {ital L}})}, which has many exotic features and surprising experimental signatures is explored.
