Pages : 3
Book Description
Based on an 87-fb{sup -1} dataset collected by the Babar detector at the PEP-II asymmetric-energy B-Factory, a search for D{sup 0}-{bar D}{sup 0} mixing has been made using the semileptonic decay modes D*{sup +} {yields} {pi}{sup +}D{sup 0}, D{sup 0} {yields} Ke{nu} (+c.c.). The use of these modes allows unambiguous flavor tagging and a combined fit of the D{sup 0} decay time and D*{sup +}-D{sup 0} mass difference ({Delta}M) distributions. The high-statistics sample of unmixed semileptonic D{sup 0} decays is used to model the {Delta}M distribution and time-dependence of mixed events directly from the data. Neural networks are used to select events and reconstruct the D{sup 0}. A result consistent with no charm mixing has been obtained, R{sub mix} = 0.0023 {+-} 0.0012 {+-} 0.0004. This corresponds to an upper limit of R{sub mix}

Book Description
Based on a dataset acquired by the BABAR experiment running on and near the {Upsilon}(4S) resonance from 1999-2002, an upper limit is set on the rate of D{sup 0}-{bar D}{sup 0} mixing using the decay mode D*{sup +} {yields} D{sup 0}{pi}{sup +}, followed by a semi-leptonic decay of the D{sup 0}. Results are compared to previous BABAR analysis using hadronic decays. We also set limits on the flavor-changing neutral current decays D{sup 0} {yields} e{sup +}e{sup -} ({mu}{sup +}{mu}{sup -}) and the lepton-flavor violation decays D{sup 0} {yields} e{sup {+-}}{mu}{sup {-+}}.

The use of these modes allows unambiguous flavor tagging and a combined fit of the D[sup 0] decay time and D*[sup +]-D[sup 0] mass difference ([Delta]M) distributions. The high-statistics sample of unmixed semileptonic D[sup 0] decays is used to model the [Delta]M distribution and time-dependence of mixed events directly from the data. Neural networks are used to select events and reconstruct the D[sup 0]. A result consistent with no charm mixing has been obtained. R[sub mix] = 0.0023 [+-] 0.0012 [+-] 0.0004.

Hot Hadronic Matter
Author: Jean Letessier
Publisher: Springer Science & Business Media
ISBN: 1461519454
Category : Science
Languages : en
Pages : 569
Book Description
The past decade has seen the development of the operational understanding of fun damental interactions within the standard model. This has detoured our attention from the great enigmas posed by the dynamics and collective behavior of strongly interacting particles. Discovered more than 30 years ago, the thermal nature of the hadronic particle spectra has stimulated considerable theoretical effort, which so far has failed to 'confirm' on the basis of microscopic interactions the origins of this phenomenon. However, a highly successful Statistical Bootstrap Model was developed by Rolf Hagedorn at CERN about 30 years ago, which has led us to consider the 'boiling hadronic matter' as a transient state in the trans formation of hadronic particles into their melted form which we call Quark-GIuon-Plasma (QGP). Today, we return to seek detailed understanding of the thermalization processes of hadronic matter, equipped on the theoretical side with the knowledge of the fundamental strong interaction theory, the quantum chromo-dynamics (QCD), and recognizing the im portant role of the complex QCD-vacuum structure. On the other side, we have developed new experimental tools in the form of nuclear relativistic beams, which allow to create rather extended regions in space-time of Hot Hadronic Matter. The confluence of these new and recent developments in theory and experiment led us to gather together from June 27 to July 1, 1994, at the Grand Hotel in Divonne-Ies-Bains, France, to discuss and expose the open questions and issues in our field.
