Results of time evolution analyses of B-decays at Belle

We report results of proper-time evolution analyses of B decays at Belle, based on a 29.1/fb data sample recorded at the Upsilon (4S) resonance. These results include measurements of sin2phi_1, the lifetime of B-mesons, and the mass-difference between two mass eigenstates of the B^0-B^0-bar system (Delta-m_d). Delta-m_d is measured using three different methods: fully reconstructed hadronic modes, a fully reconstructed semi-leptonic mode, and a partially reconstructed D*+ pi- mode.Comment: 13 pages, contributed to the proceedings of the Fifth KEK Topical Conference, 20-22, Nov. 2001, Tsukuba, Japa

Macroscopic thermodynamics of equilibrium characterized by power-law canonical distributions

Macroscopic thermodynamics of equilibrium is constructed for systems obeying power-law canonical distributions. With this, the connection between macroscopic thermodynamics and microscopic statistical thermodynamics is generalized. This is complementary to the Gibbs theorem for the celebrated exponential canonical distributions of systems in contact with a heat bath. Thereby, a thermodynamic basis is provided for power-law phenomena ubiquitous in nature.Comment: 12 page

The CPTPP and Digital Trade: Embracing E-Commerce Opportunities for SMEs in Japan and Canada

One of the most innovative features of the CPTPP is its material on digital trade, especially its chapter on e-commerce which contains a number of provisions aimed at enhancing this vital sector of the economy by eliminating distortive trade barriers such as restrictions on data transfer and data localization requirements. Such provisions should be important to the CPTPP’s two largest parties: Canada and Japan, both of which are highly advanced economies seeking to enhance their digital trade capacity across the Pacific Rim. This paper explores the main features of the CPTPP concerning digital trade from the perspective of Small and Medium Sized Enterprises (SMEs) in Canada and Japan. Such businesses have a poor track record of e-commerce uptake and may be disadvantaged relative to their larger competitors which enjoy dominance in the online marketplace. Whether or not the CPTPP will assist these businesses while striking the right balance between an open internet and safeguarding of issues such as privacy is a matter of some debate

Macroscopic proof of the Jarzynski-Wojcik fluctuation theorem for heat exchange

In a recent work, Jarzynski and Wojcik (2004 Phys. Rev. Lett. 92, 230602) have shown by using the properties of Hamiltonian dynamics and a statistical mechanical consideration that, through contact, heat exchange between two systems initially prepared at different temperatures obeys a fluctuation theorem. Here, another proof is presented, in which only macroscopic thermodynamic quantities are employed. The detailed balance condition is found to play an essential role. As a result, the theorem is found to hold under very general conditions.Comment: 9 pages, 0 figure

Quantum Statistical Effects on Fusion Dynamics of Heavy-Ions

In order to describe the fusion of two very heavy nuclei at near barrier energies, a generalized Langevin approach is proposed, which incorporates the quantum statistical fluctuations in accordance with the fluctuation and dissipation theorem. It is illustrated that the quantum statistical effects introduce an enhancement of the formation of compound nucleus, though the quantum enhancement is somewhat less pronounced as indicated in the previous calculations.Comment: 17 pages, 6 figure

T Violation in Baryonic B Decays

We study $T$ violation in the three-body charmless baryonic decay of \bar B^0 \ra \Lambda \bar p \pi^+ through the $T$-odd triple product correlation in the standard model. We find that the $T$ violating asymmetry is 10%, which is accessible to the current B factories at KEK and SLAC, while the CP violating one 1.1%. We emphasize that this triple product correlation would be the first measurable direct $T$ violating effect predicted in the standard model.Comment: 4 pages, 1 table, parallel talk given at International Conference on QCD and Hadronic Physics, Beijing, China, 16-20 Jun 200
