Gauge invariance in 2Pi effective actions

Description: (Abstract damaged) The 2PI (two particle irreducible) effective action is a general field theoretic tool for addressing this problem. In constructing it one introduces sources for both the fields and their two-point bilinears.

Technical progress report of the Indiana University High Energy Physics Group, December 1, 1976--November 30, 1977. [Summaries of research activities at Indiana University]

Description: Since the beginning of the ERDA contract year (Dec. 1, 1976), the Indiana High Energy Physics Group has been actively participating in experimental programs at SLAC, Fermilab, CERN, and the Argonne ZGS. The SLAC effort (E103) is a search for exotic mesons. The polarization program at Fermilab's internal target (CO) area involves polarization measurements in pp ..-->.. pp (E313) and pp ..-->.. pX (E522). The contribution to the Multiparticle Spectrometer at Fermilab is a major ingredient in a series of experiments (E110/260/523/557) studying low-p/sub t/ and high-p/sub t/ hadron-hadron collisions. At CERN work is carried out with a Saclay group at the SPS to investigate properties of psi meson production in experiment WAll. The Argonne ZGS endeavor (E399) is to measure various inclusive polarizations, complementing Fermilab E522 work. Also participation is given in design work on a PEP proposal. A discussion of these experiments is given.

Relativistic kinematics

Description: This memo is an expansion of an informal memo prepared for the Table on Relativistic Kinematics first appearing in the 1974 edition of the ''Review of Particle Properties,'' Particle Data Group, Phys. Lett. 50B, April 1974. The formulas that appeared in the table on pages 20 to 23 are demonstrated. New formulas are presented as well. Finally, an updated table is given.

Factorization for high-energy scattering

Description: The author demonstrates that the amplitude of the high-energy scattering can be factorized in a product of two independent functional integrals over ''fast'' and ''slow'' fields which interact by means of Wilson-line operators -- gauge factors ordered along the straight lines.

Description: Analysis of particle interaction in the laboratory frame of storage rings is often complicated by the fact that particle motion is relativistic, and that reference particle trajectory is curved. Rest frame of the reference particle is a convenient coordinate system to work with, within which particle motion is non-relativistic. We have derived the equations of motion in the beam rest frame from the general relativity formalism, and have successfully applied them to the analysis of crystalline beams [1].

Physics Regimes in the Fusion Ignition Research Experiment (FIRE)

Description: Burning plasma science is recognized widely as the next frontier in fusion research. The Fusion Ignition Research Experiment (FIRE) is a design study of a next-step burning plasma experiment with the goal of developing a concept for an experimental facility to explore and understand the strong nonlinear coupling among confinement, magnetohydrodynamic (MHD) self-heating, stability, edge physics, and wave-particle interactions that is fundamental to fusion plasma behavior. This will require plasmas dominated by alpha heating (Q greater than or equal to 5) that are sustained for a duration comparable to characteristic plasma timescales (greater than or equal to 10) tau(subscript ''E''), approximately 4 tau(subscript ''He''), approximately 2 tau(subscript ''skin''). The work reported here has been undertaken with the objective of finding the minimum size (cost) device to achieve these physics goals.

Relativistic Generalization of the Post-Prior Equivalence for Reaction of Composite Particles

Description: In the non-relativistic description of the reaction of composite particles, the reaction matrix is independent of the choice of post or prior forms for the interaction. We generalize this post-prior equivalence to the relativistic reaction of composite particles by using Dirac's constraint dynamics to describe the bound states and the reaction process.

Description: The authors consider glueball-(hybrid) meson mixing for the low-lying four pseudovector states. The h{sub 1}{prime}(1380) decays dominantly to K*K with some presence in {rho}{pi} and {omega}{eta}. The newly observed h{sub 1}(1600) has a D- to S-wave width ratio to {omega}{eta} which makes its interpretation as a conventional meson unlikely. They predict the decay pattern of the isopartner conventional or hybrid meson b{sub 1}(1650). A notably narrow s{bar s} partner h{sub 1}{prime}(1810) is predicted.

String solitons and singularities of K{sub 3}

Description: T-duality in string theory is discussed in this paper. Two issues are emphasized: (1) How the type IIA string on {bold R}{sup 6} x K{sup 3} behaves near the orbifold singularity where the 2-cycle degenerates. (2) How the enhancement of gauge symmetry occurs non-perturbatively along the line of Storminger`s proposal. Since the details have been presented elsewhere, here I only describe the main details of these discussions.

Description: The past few years have seen an evolution in the study of rare K decays from a concentration on explicitly Standard Model (SM) violating decays such as K{sub L}{sup 0} {r_arrow} {mu}e, to one on SM-allowed but suppressed decays such as K {r_arrow} {pi}{nu}{bar {nu}}, in which short-distance interactions are dominant. There are also a number of recent experimental and theoretical studies of long-distance-dominated decays, but they do not have space to cover these, with the exception of those that are needed in the discussion of the short-distance-dominated processes.
