General Search for New Phenomena in ep Scattering at HERA

Martin Wessels

A model-independent search for deviations from the Standard Model prediction has been performed in e+p and e-p collisions at HERA using H1 data. All experimentally measurable event…

Search for Single Top Quark Production in ep Collisions at HERA

H1 Collaboration

A search for single top quark production is performed in e^\pm p collisions at HERA. The search exploits data corresponding to an integrated luminosity of 118.3 pb^-1. A model for…

Production rate of bb(bar) quark pairs from gluons and bb(bar)bb(bar) events in hadronic Z Decays

The OPAL collaboration, G. Abbiendi

The rates are measured per hadronic Z decay for gluon splitting to bb(bar) quark pairs, g_bb, and of events containing two bb(bar) quark pairs, g_4b, using a sample of four-jet eve…

Photonic events with missing energy in e+e- collisions at sqrt(s)=189 GeV

G. Abbiendi, the OPAL collaboration

Photonic events with large missing energy have been observed in e+e- collisions at a centre-of-mass energy of 189GeV using the OPAL detector at LEP. Results are presented for event…

Search for Neutral Higgs Bosons in e+e- Collisions at sqrt(s) ~189GeV

The OPAL collaboration, G. Abbiendo

A search for neutral Higgs bosons has been performed with the OPAL detector at LEP, using approximately 170 pb-1 of e+e- collision data collected at sqrt(s)~189GeV. Searches have b…

Measurement of triple gauge boson couplings from W^+W^- production at sqrt{s} = 172 GeV

The OPAL Collaboration, K. Ackerstaff et al

We present measurements of triple gauge boson coupling parameters using data recorded by the OPAL detector at LEP2 at a centre-of-mass energy of 172 GeV. A total of 120 W-pair cand…
