Results and Perspectives in Particle Physics,
Recent measurements in the charm sector at BABAR are reviewed. The scope of the presentation includes the observation of two new narrow mesons in the D + s π 0 and D + s π 0 γ final states as well as the measurement of D 0-D 0 mixing parameters by means of two methods: using the doubly-Cabibbo-suppressed D 0 decay to K + π − and using the ratios of lifetimes extracted from samples of D 0 mesons...
متن کاملComputational Analogy: Some Results and Perspectives*
The Greek word analogy (gr. analogia) means correct corelation between two or more objects as a proportionality or correspondence. The logical reasoning by analogy is one of the most efficient means in gaining new knowledge and decision making. The investigations on analogy in the field of artificial intelligence (AI) start at the beginning of the 60-ies, when attempts have been made to solve s...
متن کامل“glueballs”: Results and Perspectives from the Lattice
The gluons of QCD should not only manifest themselves in deep inelastic scattering but also affect the hadron spectrum. In the sector of pseudoscalar mesons this is indeed the case: gluodynamics results in the axial anomaly which in turn implies a big mass gap between the singlet η and the octet of SU(3) Goldstone pions. In addition to such indirect effects, QCD in principle offers the possibil...
متن کاملNumerical Homogenization: Survey, New Results, and Perspectives
Abstract. These notes give a state of the art of numerical homogenization methods for linear elliptic equations. The guideline of these notes is analysis. Most of the numerical homogenization methods can be seen as (more or less different) discretizations of the same family of continuous approximate problems, which H-converges to the homogenized problem. Likewise numerical correctors may also b...
متن کاملGravitational microlensing: results and perspectives in brief
Basics of standard theory of microlensing are introduced. Results of mi-crolensing observations toward Magellanic Clouds and relations with dark matter (DM) problem in our Galaxy are described. Pixel microlensing observations and recent discoveries of planets with microlensing observations are listed. Gravitational lensing is based on a simple physical phenomenon that in a gravitational field a...
