چکیده

We have searched for the production of a selectron and a squark in ep collisions at a center-of-mass energy of 300 GeV using the ZEUS detector at HERA. The selectron and squark are sought in the direct decay into the lightest neutralino in the framework of supersymmetric extensions to the Standard Model which conserve R-parity. No evidence for the production of supersymmetric particles has been found in a data sample corresponding to 46.6 pb of integrated luminosity. We express upper limits on the product of the cross section times the decay branching ratios as excluded regions in the parameter space of the Minimal Supersymmetric Standard Model.

Searches for Supersymmetry at Hera

Supersymmetric signals were searched for in e + p collisions collected by H1 and ZEUS in 1994 ! 1997 corresponding to an integrated luminosity of about 40 pb ?1 per experiment at a center-of-mass energy of 300 GeV. Within the framework of minimal supersym-metric extensions to the Standard Model which conserve R-parity, ZEUS found no evidence for the production of selectron and squark decaying d...

Search for RPV Gaugino and Gravitino Production at HERA

In R-parity violating supersymmetry a gaugino can be produced at HERA by the t-channel exchange of a selectron between the beam positron or electron and an initial quark from the beam proton. In the generic MSSM model the gaugino can decay in a cascade into two quarks and an (anti)lepton. For this model a search in the e±-channel has been performed with the ZEUS detector using combined e±p-data...

Search for RPV Squark Production at HERA

The ep collider HERA is ideally suited to search for new particles which could be produced resonantly via the fusion of the incoming 27.5 GeV electron and a quark from the incoming 920 GeV proton. Particle masses up to the electron-proton centre-of-mass energy, √ s = 318 GeV, are kine-matically accessible. Two collider experiments, H1 and ZEUS, have searched for the production of squarks, the s...

Search for Squark Production in R-Parity Violating Supersymmetry at HERA

Search for Squark Production in R-Parity Violating Supersymmetry at HERA This thesis describes a search for squarks in supersymmetric models which allow R-parity violation. Electron-proton and positron-proton collisions taken at a centre of mass energy of 320GeV have been investigated using the H1 detector at HERA. The data correspond to an integrated luminosity of 64.3 pb−1 for ep collisions a...

Exotic Physics at Hera

A search for excited neutrinos, the analysis of multi-lepton final states, a search for doubly charged Higgs production and a general search for high-P T phenomena at HERA are reported. The searches use data samples of e ± p collisions with a centre-of-mass energy √ s = 320 GeV collected by the H1 and ZEUS experiments at HERA in the years 1994-2005 with integrated luminosities up to L = 296 pb ...
