DOWNLOAD EBOOKPreliminary results on searches for new particles beyond the Standard Model are presented. The data were taken by the CDF collaboration at the Fermilab {bar p}p collider at a center of mass energy of 1.8 TeV. Limits on the masses of the gluino and squark in a minimal supersymmetric theory are given. The 90% confidence level asymptotic lower mass limits on each are 150 GeV/c2. A special data run was taken to search for the diffractively produced sextet quark state?6. An?6 with a mass larger than 20 GeV/c2 is excluded at the 95% confidence level. Limits are also set on the pair-production of massive stable charged particles. Unit-charged particles belonging to spin 1⁄2 color triplets with masses between 50 and 139 GeV/c2 are ruled out at the 95% confidence level as are charge 2/3 particles with masses between 50 and 116 GeV/c2 and charge 4/3 particles with masses between 50 and 140 GeV/c2. 5 refs., 3 figs.

DOWNLOAD EBOOKWe present results of recent searches for new physics using the CDF detector at the Fermilab Tevatron. Presented are searches for Higgs →??, as well as more general searches in?? + X where X is /E{sub T}, jets, charged leptons, b-quarks or extra photons. The CDF ee??/E{sub T} candidate event is discussed along with estimates of the expected rates in the Standard Model. Other searches for SUSY, Higgs and Technicolor look for particles which decay to vector bosons and b-quarks.

DOWNLOAD EBOOKThe proceedings of this series of annual symposia represent an extensive summary of the experimental and theoretical status of high energy physics at hadron colliders. This volume discusses the latest results on top and beauty physics, QCD, electroweak physics and searches for new particles. The prospects of this field for LHC, Tevatron and Hera machines are also reported.

DOWNLOAD EBOOKNuclear double beta decay is - together with proton decay - one of the most promising tools for probing beyond-the-standard-model physics on beyond-accelerator energy scales. It is already probing the TeV scale, on which new physics should manifest itself according to theoretical expectations. Only in the early 1980s was it known that double beta decay yields information on the Majorana mass of the exchanged neutrino. At present, the sharpest bound for the electron neutrino arises from this process. It is only in the last 10 years that the much more far-reaching potential of double beta decay has been discovered. Today, the potential of double beta decay includes a broad range of topics that are equally relevant to particle physics & astrophysics, such as masses of heavy neutrinos, the sneutrino, SUSY models, compositeness, leptoquarks & right-handed W bosons. This invaluable book outlines the development of double beta research from its beginnings until its most recent achievements, & also presents the outlook for its highly exciting future. Readership: Particle physicists, nuclear physicists & astrophysicists.

DOWNLOAD EBOOKNuclear double beta decay is one of the most promising tools for probing beyond-the-standard-model physics on beyond-accelerator energy scales. It is already now probing the TeV scale, on which new physics should manifest itself according to theoretical expectations. Only in the early 1980s was it known that double beta decay yields information on the Majorana mass of the exchanged neutrino. At present, the sharpest bound for the electron neutrino mass arises from this process. It is only in the last 10 years that the much more far-reaching potential of double beta decay has been discovered. Today, the potential of double beta decay includes a broad range of topics that are equally relevant to particle physics and astrophysics, such as masses of heavy neutrinos, of sneutrinos, as SUSY models, compositeness, leptoquarks, left-right symmetric models, and tests of Lorentz symmetry and equivalence principle in the neutrino sector. Double beta decay has become indispensable nowadays for solving the problem of the neutrino mass spectrum and the structure of the neutrino mass matrix — together with present and future solar and atmospheric neutrino oscillation experiments. Some future double beta experiments (like GENIUS) will be capable to be simultaneously neutrino observatories for double beta decay and low-energy solar neutrinos, and observatories for cold dark matter of ultimate sensitivity.This invaluable book outlines the development of double beta research from its beginnings until its most recent achievements, and also presents the outlook for its highly exciting future.
