Catalysis Of Flavor Nonconservation By Monopoles, V. Parameswaran Nair
Catalysis Of Flavor Nonconservation By Monopoles, V. Parameswaran Nair
Publications and Research
A simple argument based on current algebra is given to show how monopoles can lead to baryon decay and other flavor-changing processes.
Order Of Phase Transitions In A Field Theory, V. Parameswaran Nair
Order Of Phase Transitions In A Field Theory, V. Parameswaran Nair
Publications and Research
The relation between the gauge or global nature of a symmetry being broken and the order of the associated phase transition is clarified. First-order phase transitions in gauge theories are related to the asymptotic freedom of the Φ3 interaction in six dimensions. Spontaneous violation of lepton number in the standard electroweak theory provides a nontrivial illustration of our results.
Second-Order Phase Transitions, Inflationary Universe, And Formation Of Galaxies, V. Parameswaran Nair
Second-Order Phase Transitions, Inflationary Universe, And Formation Of Galaxies, V. Parameswaran Nair
Publications and Research
At the critical point of a second-order phase transition, statistical fluctuations are correlated and enhanced in amplitude. We explore this phenomenon in the early universe as a possible mechanism for the formation of galaxies. In an inflationary universe, such dynamical effects on galactic scales are consistent with the constraints imposed by the horizon. Spontaneous breakdown of lepton number provides a model where these ideas are realized. The two-point correlation function for density fluctuations is calculated and agrees with the observed correlation for galaxies. An estimate of the density contrast is shown to be of the required magnitude.

Generalized Bohr-Sommerfeld Rules For Anomalies With Applications To Symmetry Breakdown And Decoupling, A. P. Balachandran, V. P. Nair, C. G. Trahern
Generalized Bohr-Sommerfeld Rules For Anomalies With Applications To Symmetry Breakdown And Decoupling, A. P. Balachandran, V. P. Nair, C. G. Trahern
Publications and Research
In the presence of anomalies, the requirement that a classical symmetry group G has a proper action on the fermion measure or in the effective Lagrangian description imposes Bohr-Sommerfeld conditions on the anomalies, and often implies that G is broken to a subgroup H as well. We show these results in this paper and apply them to QCD and SU(5). In particular, constraints on the QCD order parameter are derived, and an argument is presented which suggests that the breakdown of the chiral flavor symmetry and the emergence of some sort of generation structure in QCD may be natural.

Publications and Research
The work of Skyrme has shown that the SU(2)×SU(2) chiral model has nontrivial topological sectors which admit solitons for generic chiral Lagrangians. In this paper, we study such models in the presence of baryon fields. The baryon number and strangeness of the solitons, and the bound states of the nucleon to the soliton are investigated. It is found that long-lived levels with large baryon number B and strangeness (≳6 in magnitude) and masses somewhere in the range 1.8 to 5.6 GeV must exist. Some of these levels have half-integral electric charge and exotic relation between B and spin s (e.g., …

The Theory And Synthesis Of [2.2.2] Propellane, Theodore Mark Prociv
The Theory And Synthesis Of [2.2.2] Propellane, Theodore Mark Prociv
Dissertations, Theses, and Capstone Projects
INDO calculations indicated that the triplet state of dimethylene cyclohexane could rearrange to gometrically relaxed triplets which should collapse preferentially to the ground state [2.2.2] Propellane. A mercury sensitized photolysis of the dimethylene cyclohexane did in fact result in detectable quantities of the propellane, trapped as 1,4 dibromobicyclo octane. Synthesis of 1,4 dibromobicyclo octane and 1,1,6,6 tetradeuterodimethylene-cyclohexane are presented in the dissertation. Included in the dissertation are the results of INDO calculations of various propellane isomers having nitrogens and borons in the bridgehead positions.

Publications and Research
Skyrme has shown that the SU ⊗ SU(2) chiral model has nontrivial topological sectors with static solutions for suitable Lagrangians. The baryon number B and strangeness of these sectors have been studied, and the existence of bound states of the nucleon field to the lightest solitons is shown. It is found that there must be long-lived levels with |B|≳6 and |s|≳6 and 1.8 GeV≲m≲5.6 GeV, some having half-integral charge and exotic relation between B and s, that can be pair produced in, say, e+e− collisions.

The Abelian and non-Abelian gauge potentials Auv are known to describe chiral fields. Here we study their interactions with dual extended objects. The region occupied by these objects is shown to behave like a distinct phase of chiral fields which is nondissipative under suitable geometric conditions. A method for the realization of the 't Hooft algebra in these systems is outlined. The concept of electric and magnetic duality in electromagnetism is generalized to chiral fields with values in a symmetric space.

In a recent paper, Slansky et al. have suggested that SU(3)c may be broken to SO(3) X Z, in order to explain the possible existence of fractionally charged states. We point out that there are low mass monopoles associated with such a symmetry breakdown and discuss their properties. Such states may be observable at LEP if not at PETRA energies.

AN INTEGRATED INFORMATION CAPABILITY FOR POLICY ANALYSIS INTRODUCTION AND SUMMARY 0 Consideration of optimum organizational structures for maximum effectiveness of quantitative information flows in support of policy decisions seems to be haphazard, nonexistent, or at best secondary to other organizational issues. As a result we undertook to examine data bases, data flows, and their related models and analyses, with a view to developing reconnnended organizational characteristics. "Study of information organizations and their supporting data and models reveals that common data bases, models and analysis all coincide with common uses. Further, common use equates to common levels of organizational (dis)aggregation. The …
