No Vacuum Cerenkov Radiation Losses In The Timelike Lorentz-Violating Chern-Simons Theory, Karl Schober, Brett David Altschul Oct 2015

No Vacuum Cerenkov Radiation Losses In The Timelike Lorentz-Violating Chern-Simons Theory, Karl Schober, Brett David Altschul

Faculty Publications

In a Lorentz- and CPT-violating modification of electrodynamics that includes a timelike Chern-Simons term, there are no energy losss through vacuum Cerenkov radiation. A charge moving with a constant velocity does not lose energy, because of an unusual cancellation. Higher frequency modes of the electromagnetic field carry away positive energy, but lower frequency modes carry away a compensating negative amount of energy.


Nuclear Parton Distributions And The Drell-Yan Reaction, S. A. Kulagin, Roberto Petti Apr 2015

Nuclear Parton Distributions And The Drell-Yan Reaction, S. A. Kulagin, Roberto Petti

Faculty Publications

We discuss the nuclear parton distribution functions on the basis of our recently developed semi-microscopic model, which takes into account a number of nuclear effects including Fermi motion and nuclear binding, nuclear meson-exchange currents and off-shell corrections to bound nucleon distributions as well as nuclear shadowing effect. We also discuss application to the nuclear Drell-Yan process and compare our predictions with data from the E772 and E866 experiments.

We present in detail the scientific objectives in fundamental physics of the Space–Time Explorer and QUantum Equivalence Space Test (STE–QUEST) space mission. STE–QUEST was pre-selected by the European Space Agency together with four other missions for the cosmic vision M3 launch opportunity planned around 2024. It carries out tests of different aspects of the Einstein Equivalence Principle using atomic clocks, matter wave interferometry and long distance time/frequency links, providing fascinating science at the interface between quantum mechanics and gravitation that cannot be achieved, at that level of precision, in ground experiments. We especially emphasize the specific strong interest of performing …
