The Standard Model cannot explain neutrino masses and oscillations, does
not provide a candidate for dark matter particle and does not explain
why the universe contains more matter than antimatter. A unified
solution of these problems appears if the neutral fermion sector of the
Standard Model is constructed in analogy with the structures we have in
quarks or in charged leptons. Namely,...

A new method of delivering a monochromatic electron beam to the LHC interaction points is proposed. This method could enlarge the scope of the research programme of the present LHC detectors, by including the research programme of the electron-proton and electron-ion collisions. The carrier of the electron beam, over the full acceleration cycle, is the heavy ion beam. The storage of such a...

SPS Hadrons and Ions
The possibility to study the production of J/ψ mesons in the fixed target experiments with proton and lead beams at LHC has been investigated. At SPS energies the normal nucleus suppression of J/ψ in proton-nucleus collisions and anomalous suppression in central lead-lead collisions was observed in NA50 experiment. The anomalous suppression for central indium-indium events at SPS was confirmed...

High energy external beams at LHC offer unique opportunities for specialized experiments. Besides providing beams of charmed mesons which may be used for total charm cross section measurements one such experiment is the determination of the magnetic moment of charmed baryons. We will present the physics and a possible technique for such a measurement, which constitutes a challenge in...

The Large Hadron Collider (LHC) will generate two counter rotating 7 TeV proton beams, each containing 362 MJ energy that is sufficient to melt 500 kg copper. Safety of operation is an extremely important issue when working with such powerful beams. Any uncontrolled release of a small fraction of the beam energy can cause considerable damage to the equipment. A worst case scenario could be...

A new scheme of plasma wakefield accelerator was recently proposed (A. Caldwell et al., arXiv, acc-ph: 0807.4599). The idea is to use existing high-energy proton bunches to drive a plasma wakefield. The strong plasma field then accelerates a trailing electron bunch to high energies. 2D and 3D Particle-in-Cell simulations show that a proton bunch with particle energy of 1 TeV, a bunch length...
