Book excerpt: High precision measurements of the differential cross sections for $\pi^0$ photoproduction at forward angles for two nuclei, $^{12}$C and $^$Pb, have been performed for incident photon energies of 4.9 - 5.5 GeV to extract the ${\pi^0 \to \gamma\gamma}$ decay width. The experiment was done at Jefferson Lab using the Hall~B photon tagger and a high-resolution multichannel calorimeter. The ${\pi^0 \to \gamma\gamma}$ decay width was extracted by fitting the measured cross sections using recently updated theoretical models for the process. The resulting value for the decay width is $\Gamma{(\pi^0 \to \gamma\gamma)} = 7.82 \pm 0.14 ~({\rm stat.}) \pm 0.17 ~({\rm syst.}) ~{\rm eV}$. With the 2.8\% total uncertainty, this result is a factor of 2.5 more precise than the current PDG average of this fundamental quantity and it is consistent with current theoretical predictions.

This book was released on 2009-04-14 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: On September 27 – October 3, 2008 the NATO Advanced Research Workshop (ARW) on progress in high-energy physics and nuclear safety was held in Yalta, Crimea (see: http://crimea.bitp.kiev.ua and http://arw.bitp.kiev.ua). Nearly 50 leading experts in high-energy and nuclear physics from Eastern and Western Europe as well as from North America participated at the Workshop. The topics of the ARW covered recent results of theoretical and experimental studies in high-energy physics, accelerator, detection and nuclear technologies, as well as problems of nuclear safety in high-energy experimentation and in nuclear - dustry. The forthcoming experiments at the Large Hadron Collider (LHC) at CERN and cosmic-ray experiments were among the topics of the ARW. An important aspect of the Workshop was the scienti?c collaboration between nuclear physicists from East and West, especially in the ?eld of nuclear safety. The present book contains a selection of invited talks presented at the ARW. The papers are grouped in two parts.

This book was released on 2009 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: The Standard Model is the best current description of fundamental interactions and particles; however, the Standard Model has certain shortcomings which have driven particle physicists for the last 30 years to search for phenomena which provide evidence for the next theory beyond the Standard Model. To this end, using the BaBar detector, we search for evidence of the rare decay D* -> D0[pi];D0->[gamma][gamma]. The branching fraction of this decay is enhanced up to 200 times the standard model prediction in certain beyond-the-Standard-Model theories. A measurement of a significant branching fraction would provide evidence for a new theory of particle physics. We describe our search for this rare decay and an improved measurement of the associated decay, B(D0-> [pi]0 [pi]0) using an integrated luminosity corresponding to 470.5 fb−1 of e e− data collected by the BaBar detector at the PEP-II asymmetric ee− collider at SLAC from 1999-2007. We place an upper limit of B(D0->[gamma][gamma]) 2.51 X 10−6 at 90% confidence level and find B(D0-[pi]0[pi]0) = (8.4 " 0.1 " 0.4 " 0.3) X 10−4.

Available in PDF, EPUB and Kindle. Book excerpt: Particle physics is considered to be one of the most fundamental subject in physical science. Elementary particles and forces between them govern the behavior of Nature. To understand the nature of the interactions among the elementary particles (quarks and leptons) is the central question in particle physics. Quarks and leptons are thought to be described within a unified framework by the standard electro-weak theory of SU(2)xU(l) using the Cabibbo. Kobayashi-Maskawa matrix. Many particle physicists wish to establish the consistency of this standard theory by determining the C-K-M matrix elements experimentally.
