Limit on the B0->rho0rho0 Branching Fraction and Implications for the CKM Angle alpha

The BABAR Collaboration, B. Aubert et al

We search for the decay B0 -> rho0 rho0 in a data sample of about 227 million Upsilon(4S)-> BBbar decays collected with the BABAR detector at the PEP-II asymmetric-energy e+e- coll…

Measurement of Branching Fractions and Charge Asymmetries for Exclusive B Decays to Charmonium

B. Aubert, BABAR Collaboration

We report measurements of branching fractions and charge asymmetries of exclusive decays of neutral and charged B mesons into two-body final states containing a charmonium state an…

Experimental investigation of amplitude and phase quantum correlations in a type II OPO above threshold: from the non-degenerate to the degenerate operation

Julien Laurat, Thomas Coudreau, Laurent Longchambon +1

We describe a very stable type II optical parametric oscillator operated above threshold which provides 9.7 0.5 dB (89%) of quantum noise reduction on the intensity differenc…

Logarithmic Trace of Toeplitz Projectors

Louis Boutet de Monvel

We prove that the trace of the logarithmic term of the Toeplitz kernel on a contact manifold is a contact invariant, generalizing K. Hirachi's invariant for the Szego kernel on a C…

Large deviations for rough paths of the fractional Brownian motion

Annie Millet, Marta Sanz-Solé

Starting from the construction of a geometric rough path associated with a fractional Brownian motion with Hurst parameter given by Coutin and Qian (2002), we…

Radiodetection of Cosmic Ray Extensive Air Showers

D. Ardouin, A. Belletoile, D. Charrier +12

We present the characteristics and performance of a demonstration experiment devoted to the observation of ultra high- energy cosmic ray extensive air showers using a radiodetectio…
