[en] We use stellar dynamics arguments to constrain the relevant parameters of unparticle-inspired models of gravity. We show that resulting bounds do constrain the parameters of the theory of unparticles, as far as its energy scale satisfies the condition ΛU≥1 TeV and dU is close to unity.
[en] This article is a report on the status of the Fermilab Tevatron Project. The various phases of the project are described, and the experimental possibilities provided by them are discussed. First priority has been given to the construction of a superconducting magnet synchotron which is capable of accelerating particles to one TeV. Secondly, the project involves the construction of facilities for fixed target experiments at those energies. Finally, the Tevatron will be equipped to perform colliding proton-antiproton experiments
[en] For large superconducting accelerators in the energy range one to several TeV the requirements both for refrigeration capacity and linear extension in space are increasing enormously. Problems related to these dimensions are: size of refrigerators; transportation of coolants over long distances; two phase flow in non equigravitational lines; safety and gas storage. The most important topics are discussed and compared with existing or planned installations. (Author)
[en] Several models extending the Standard Model predict final states resulting in long-lived or unusual signatures. Many of these signatures are targeted by the search programs of the Large Hadron Collider experiments ATLAS and CMS. Recent results extracted from the 7 TeV and 8 TeV data, recorded in 2011 and 2012 respectively, are presented. So far no evidence for such signatures have been found and various model exclusions have been performed. (authors)
[en] The transverse momentum (ρ_T) spectra of hadrons measured in the pp and heavy ion collision reflect the condition of the system at the time of freeze-out. Hadrons form the bulk of particles produced and are usually the first and the easiest to be measured in a heavy ion collision experiment. The ρ_T spectra of of hadrons are very useful tools to study particle production mechanisms, thermalization and collective effects and at high ρ_T probe jet quenching effects
