Book excerpt: We present a concise review of the theoretical status of rare K →??{bar?} decays in the standard model (SM). Particular attention is thereby devoted to the recent calculation of the next-to-next-to-leading order (NNLO) corrections to the charm quark contribution of K →?+?{bar {nu}}, which removes the last relevant theoretical uncertainty from the K →?{nu}{bar {nu}} system.

This book was released on 2022-10-25 with total page 354 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a Festschrift compiled in honor of Professor Peter Suranyi, Professor Emeritus, University of Cincinnati. In a long career spanning almost 60 years, Professor Suranyi has made valuable contributions in many areas of theoretical physics, especially in the fields of strong interaction physics, quantum field theory, particle physics, statistical mechanics, lattice field theory, condensed matter physics, and particle cosmology. His important contributions range from analysis of Regge poles in quantum field theory, work on Reggeon field theory, developing improved perturbation theory methods and numerical simulation techniques, analyzing rigidity percolation and molecular clustering in network glasses, to his recent work on Bose condensate dark matter. This volume is our way of paying tribute to his scientific achievements, mentoring prowess, and his rigorous outlook on theoretical physics.

Available in PDF, EPUB and Kindle. Book excerpt: This volume contains many excellent articles presenting the most recent progress in high energy physics and the current interesting problems concerning flavor physics. The reader will see how flavor physics has become a central area of particle physics, with the Standard Model (SM) being subjected to increasingly precise experiments, and why the remaining puzzles in the SM, such as the mechanisms of symmetry breaking and CP violation, as well as fermion mass and mixing generation, all are mysteries hidden in the physics of flavor. The book also shows that flavor physics is likely to be a window for probing new physics beyond the SM for many years to come.

Book excerpt: We have observed 1 event consistent with the signature expected of the rare decay of a positive kaon to a positive pion and a neutrino anti-neutrino pair. In the examined momentum region of 211 to 230 MeV/c in the center of mass of the kaon we estimated the backgrounds to be about 0.08[+-] 0.03 events. From this observation we estimate the branching ratio to be 4.2[sub[minus]3.5][sup+9.7] x 10[sup[minus]10]. In this presentation I will explain the experiment, and the analysis techniques. I will also discuss the expected improvements in the near future from the analysis of new data sets.

Download or read book Analysis of the Semileptonic Decay D0 Anti K0 Pi Mu Nu written by Ilaria Maria Lucia Segoni and published by . This book was released on 2004 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis describes the analysis of the semileptonic decay D{sup 0} {yields} {bar K}{sup 0} {pi}{sup -} {mu}{sup +}{nu} using FOCUS data. FOCUS is a fixed target experiment at Fermilab that studies the physics of the charm quark. Particles containing charm are produced by photon-gluon fusion from the collision of a photon beam on a BeO target. The experiment is characterized by excellent vertex resolution and particle identification. The spectrometer consists of three systems for track reconstruction (two silicon systems and one multiwire proportional chamber system) and two magnets of opposite polarity. The polarity of the magnet is such that the events of e{sup +}e{sup -} pairs produced in the target (which constitutes the main background) travel through a central opening in the detectors without interactions. Particle momentum is measured from the deflection angle in the magnets. Three multicell Cerenkov counters are used for charged particle identification (for e, {pi}, K, and p). Two different tracking systems located after several interaction lengths of shielding material are used for muon identification. The energy of neutral pions and electrons is measured in two electromagnetic calorimeters, while an hadron calorimeter is used for measuring the neutron energy. During the last four years the FOCUS collaboration provided results on several charm topics: CP violation, D{sup 0}-{bar D}{sup 0} mixing, rare and forbidden decays, precision measurements of semileptonic decays, baryon and meson lifetimes, fully hadronic baryon and meson branching ratios, charm spectroscopy, Dalitz analyses of resonant structures, charm anti-charm production, QCD studies involving double charm particles, and pentaquarks. Semileptonic decays, besides having a clear signature for experiments, provide crucial information for theoretical studies. These decays carry information on the weak coupling of quarks since they can be used for measuring Cabibbo-Kobayashi-Maskawa matrix elements. Although the decay occurs through weak interaction, QCD effects due to quark confinement affect the decay amplitude. These effects can be included through the form factors, which are predicted by different theoretical approaches (quark models, lattice QCD, and sum rules). Experiments can measure form factor ratios, and from the comparison with theory they provide guidance for building a successful theory to describe hadrons.
