Title: A high energy physics perspective

Abstract

The status of the Standard model and role of symmetry in its development are reviewed. Some outstanding problems are surveyed and possible solutions in the form of additional {open_quotes}Hidden Symmetries {close_quotes} are discussed. Experimental approaches to uncover {open_quotes}New Physics{close_quotes} associated with those symmetries are described with emphasis on high energy colliders. An outlook for the future is given.

  • Feed forward and recurrent neural networks are introduced and related to standard data analysis tools. Tips are given on applications of neural nets to various areas of high energy physics. A review of applications within high energy physics and a summary of neural net hardware status are given.

  • This paper provides a regulatory perspective from the viewpoint of the potential licensee, the U.S. Department of Energy (DOE), on the National Academy of Sciences (NAS) report on Yucca Mountain standards issued in August 1995, and on how the recommendations in that report should be considered in the development of high-level radioactive waste standards applicable to Yucca Mountain. The paper first provides an overview of the DOE perspective and then discusses several of the issues that are of most importance in the development of the regulatory framework for Yucca Mountain, including both the U.S. Environmental Protection Agency (EPA) standard andmore » the U.S. Nuclear Regulatory Commission (NRC) implementing regulation. These issues include: the regulatory time frame, the risk/dose limit, the definition of the reference biosphere, human intrusion, and natural processes and events.« less
  • Young pulsars such as the Crab and Vela pulsars are the most prominent gamma-ray sources in the Galaxy, powered by the neutron star's rotational energy and the spinning magnetic field. Since the late 1960's, a large amount of data has been amassed for these pulsars. With the recent launches of ROSAT, Compton Gamma-Ray Observatory and other new instruments, many exciting new results have been reported. In this Workshop, we learned the weak and soft pulsed emission from the Vela pulsar, the possible detection of spectral turn-over at {approximately} 30 MeV, the detection of gamma-ray emission from PSR1509-58, and observation ofmore » pulse profile variability from the Crab pulsar. Soon after the Workshop, the discovery of gamma-ray pulsations from PSR1706-44 and Geminga were reported. All of these contribute to the large pool of hints that theorists need in order to explain the origin of these powerful emission. In this paper, we discuss results from the outer gap model and comparisons to observations. Section 2 gives a brief overview of the outer gap model. Section 3 discusses the high-energy spectrum from the Crab, PSR0540-693, and Vela. In Section 4, we discuss the pulse profile for pulsars with Crab-like parameters. Section 5 discusses outer gap evolution.« less
