Using supernovae from the SDSS-SN Survey we fit the shape parameter to individual SDSS passbands (g, r, i) as well as simultaneously to all passbands using SALT2. Through checking the normalized residuals, the passbands seem consistent when compared band to band. The i passband appears to deviate from the shape as measured in all passbands. There are hints of an effect for shape versus color in...

Unexpected accelerator modes were recently observed experimentally for cold cesium atoms when driven in the presence of gravity. A detailed theoretical explanation of this quantum effect is presented here. The theory makes use of invariance properties of the system, that are similar to the ones of solids, leading to a separation into independent kicked rotor problems. The analytical solution ma...

The NA48 experiment at the CERN SPS accelerator aims to measure Re(ε′/ε), the direct CP violation parameter in K → 2π decays, to the precision of 2 × 10−4. In the year 1999, the NA48 collaboration has published its first measurement based on the 1997 data. The presented result is a preliminary measurement from data collected in the 1998 run which contain 2.5 times more KL → 2π decays than the 1...

The SNR G78.2+2.1 is a prime candidate for VHE, UHE gamma emission because of its shock wave expanding into a molecular cloud thus forming the con guration of an accelerator and nearby target [1]. The HEGRA collaboration has made a detailed study of possible gamma emission using the wide angle air Cerenkov detector AIROBICC. The excellent angular resolution of AIROBICC allows for a scan for any...

We report measurements of dynamical tunneling rates of a Bose-Einstein condensate across a barrier in classical phase space. The atoms are initially prepared in quantum states that extend over a classically regular island region. We focus on the specific system of quantum accelerator modes of the kicked rotor in the presence of gravity. Our experimental data is supported by numerical simulation...

Introduction In this study, we aimed to assess the medium-term energy stability of a 6MV Elekta CompactTM linear accelerator. To the best of our knowledge, this is the first published article to evaluate this linear accelerator in terms of energy stability. As well as investigating the stability of the linear accelerator energy over a period of several weeks, the results will be useful for esti...

In a previous paper @Phys. Lett. A 182, 255 ~1993!# we showed that, for the one-parameter area-preserving Hénon map, the domain in phase space where stable motion occurs can always be computed by using the invariant manifolds emanating from the hyperbolic fixed point of period one, regardless of the value of the parameter. We present here a generalization of this result to a large class of symp...
