R-parity violation in supersymmetry gives rise to many unique experimental signatures. We describe searches with the ATLAS detector for supersymmetry with R-parity violating decays. Examples include searches for resonant sneutrino decays to an electron and a muon, and displaced vertices arising from the late decays of heavy objects with a muon in the final state. The most recent results on thes...

The results of a recent calculation of the QCD corrections to the longitudinally polarized Drell-Yan process are summarized. In addition to the parity conserving double spin asymmetry which is already accessible in the Drell-Yan production of lepton pairs at fixed target energies, we consider parity violating single spin asymmetries appearing only in the production of massive vector bosons at p...

We present a simple theory where baryon and lepton numbers are spontaneously broken at the supersymmetry scale. In this context R parity must be spontaneously broken but the theory still contains a stable field which can play the role of the cold dark matter of the Universe. We discuss the spectrum of the theory, the properties of the dark matter candidate and the predictions for direct detecti...

The present knowledge of the Dark Matter discovery and measurement potential of the LHC is reviewed, in the framework of Supersymmetry with R-parity conservation.

We study the production of (t + ¯ t)˜ g at the hadron colliders in an R-parity (R p) violating supersymmetric model. This process provides us with information not only about R p violation, but may also help us in detecting the supersymmetry itself. It is possible to detect an R p violating signal (with single gluino production) at the future hadron colliders, such as Fermilab Tevatron Run II or...

We investigate the effects of R-parity-violating LLĒ and LQD̄ operators on the production of fermion pairs at a μμ collider with high energy and luminosity. We show that comparison of angular distributions leads to useful discovery limits for the R-parity-violating couplings, especially if the exchanged sfermions turn out to be heavy. Products of these couplings can also be probed well beyond pr...

Introduction: Radiotherapy with heavy charged particles such as protons and carbon ions (hadron therapy) has been recognized as an advanced technique for the treatment of various cancers. For some indications such as pediatric and radio-resistant tumors, it is considered the preferred method. However, despite its remarkable benefits, development of hadron therapy centers in the...
