Promouvoir Une Energie Durable Pour Tous (French Fact Sheet) (open access)

Promouvoir Une Energie Durable Pour Tous (French Fact Sheet)

The Clean Energy Solutions Center, an initiative of the Clean Energy Ministerial and UN-Energy, helps governments design and adopt policies and programs that support the deployment of transformational low-carbon technologies. The Solutions Center serves as a first-stop clearinghouse of clean energy policy reports, data, and tools and provides expert assistance and peer-to-peer learning forums. This factsheet highlights key Solutions Center offerings, including 'ask an expert' assistance on clean energy policy matters, training and peer learning, and technical resources for policy makers worldwide.

Study of CP Symmetry Violation in the Charmonium-K*(892) Channel By a Complete Time Dependent Angular Analysis (BaBar Experiment) (open access)

Study of CP Symmetry Violation in the Charmonium-K*(892) Channel By a Complete Time Dependent Angular Analysis (BaBar Experiment)

This thesis presents the full-angular time-dependent analysis of the vector-vector channel B{sub d}{sup 0} {yields} J/{psi}(K{sub S}{sup 0}{pi}{sup 0})*{sup 0}. After a review of the CP violation in the B meson system, the phenomenology of the charmonium-K*(892) channels is exposed. The method for the measurement of the transversity amplitudes of the B {yields} J/{psi}K*(892), based on a pseudo-likelihood method, is then exposed. The results from a 81.9 fb{sup -1} of collected data by the BABAR detector at the {Upsilon}(4S) resonance peak are |A{sub 0}|{sup 2} = 0.565 {+-} 0.011 {+-} 0.004, |A{sub {parallel}}|{sup 2} = 0.206 {+-} 0.016 {+-} 0.007, |A{sub {perpendicular}}|{sup 2} = 0.228 {+-} 0.016 {+-} 0.007, {delta}{sub {parallel}} = -2.766 {+-} 0.105 {+-} 0.040 and {delta}{sub {perpendicular}} = 2.935 {+-} 0.067 {+-} 0.040. Note that ({delta}{sub {parallel}}, {delta}{sub {perpendicular}}) {yields} (-{delta}{sub {parallel}}, {pi} - {delta}{sub {perpendicular}}) is also a solution. The strong phases {delta}{sub {parallel}} and {delta}{sub {perpendicular}} are at {approx}> 3{sigma} from {+-}{pi}, signing the presence of final state interactions and the breakdown of the factorization hypothesis. The forward-backward analysis of the K{pi} mass spectrum revealed the presence of a coherent S-wave interfering with the K*(892). It is the first evidence of this wave in the …

The Intentional Use of Antimony and Manganese in Ancient Glasses (open access)

The Intentional Use of Antimony and Manganese in Ancient Glasses

Title and Abstract in English, French and German, while paper is in English. The use of manganese as a colorant in ancient glasses has long been recognized and the recent X-ray diffraction measurements of Turner and Rooksby have established that compounds of antimony were used extensively as opacifiers in such glasses. The analysis at Brookhaven National Laboratory of some three hundred ancient western glasses of the second millennium B.C. through the first millennium A.D., of which more than two hundred contained either or both of these elements in sufficiently great concentrations to indicate deliberate additions, not only has provided confirmation of these observation but also evidence that both of these elements were used extensively to counteract discoloration due to iron in glasses intended to be clear and colorless. As is well known in the case of manganese the different behavior of antimony in different glasses appears to depend upon its chemical valence. The technique of decolorizing glass by means of antimony was introduced at about the seventh century B.C. and the similar use of manganese became widespread during the first century A.D. In the following period through the fourth century the alternate or combined use of these decolorants forms an …
