Analogue Models for T and CPT Violation in Neutral-Meson Oscillations

Alan Kostelecky, Agnes Roberts

Analogue models for CP violation in neutral-meson systems are studied in a general framework. No-go results are obtained for models in classical mechanics that are nondissipative o…

Searching for physics beyond the Standard Model in the decay B+ -> K+K+pi-

J. Damet, P. Eerola, A. Manara +1

The observation potential of the decay B+ -> K+K+pi- with the ATLAS detector at LHC is described in this paper. In the Standard Model this decay mode is highly suppressed, while in…

Frequency Scaling of Microwave Conductivity in the Integer Quantum Hall Effect Minima

R. M. Lewis, J. P. Carini

We measure the longitudinal conductivity at frequencies GHz over a range of temperatures K with particular e…

Splitting of the Dipole and Spin-Dipole Resonances

Sam M. Austin, E. Adamides, A. Galonsky +10

Cross sections for the 90,92,94Zr(p,n) reactions were measured at energies of 79.2 and 119.4 MeV. A phenomenological model was developed to describe the variation with bombarding e…

Abrupt Transition between Thermally-Activated Relaxation and Quantum Tunneling in a Molecular Magnet

K. M. Mertes, Y. Zhong, M. P. Sarachik +5

We report Hall sensor measurements of the magnetic relaxation of Mn acetate as a function of magnetic field applied along the easy axis of magnetization. Data taken at a ser…

Coherent Sheaves on Configuration Schemes

Valery A. Lunts

We introduce and study configuration schemes, which are obtained by ``glueing'' usual schemes along closed embeddings. The category of coherent sheaves on a configuration scheme is…
