| Abstract | Signals of QCD instanton-induced processes are searched for in
deep-inelastic scattering (DIS) at the electron-proton collider HERA
in the kinematic region defined by the Bjorken-scaling
variable x > 10^{-3}, the inelasticity 0.2< y < 0.7 and the photon
virtuality 150 < Q^2 < 15000 GeV^2. The search is performed using H1 data
corresponding to an integrated luminosity of ~350 pb^{-1}. Several
observables of the hadronic final state of the events are exploited
to identify a potentially instanton-enriched domain. Two Monte Carlo
models, RAPGAP and ARIADNE, are used to estimate the background from the
standard DIS processes, and the instanton-induced scattering processes
are modeled by the program QCDINS. In order to extract the expected
signal a multivariate data analysis technique is used. |
