Derivation of the critical temperature for the superfluid phase of hadronic matter
Abstract We give a quantitative derivation of the temperature at which superfluidity of hadronic matter ends. Using considerations similar to those used by Landau for 4 He, we find T c ⩽ 190 MeV in close agreement with Hagedorn's “limiting” temperature.

A Decade of Tests of Grand Unified Theories
This paper considers from an empirical point of view: (i) the agreement between experiment and the grand unified theory (SU(5)) prediction of sin 2γW; (ii) the results of the most recent searches for baryon number and lepton number non-conservation; (iii) possible lepton structure; and (iv) possible electric charge non-conserving processes.

Some Recent Advances in Neutrino Physics
One answer to questions concerning the subject matter of elementary particle physics and its position within the physical sciences is that particle physics is the study of creation. To justify this idea, at least in part, consider the “big bang” model of creation of the universe. In that model the primeval fireball involved very high temperatures, estimated to be greater than 1011 degrees Kelvin (°K), which is to be compared with the interior temperature of the sun at about 107 degrees Kelvin. We believe the sun to be a nuclear furnace, generating its energy by individual nuclear interactions in the million electron volt (MeV) energy range. In the “big bang” the energies involved in the individual particle interactions would have been more than 104 times larger than in the sun, and thus in the tens of giga-electron volts (GeV). This is precisely the energy region of present-day high energy or elementary particle physics laboratory experiments. In this sense, then, laboratory experiments that study, even indirectly, lepton-lepton scattering or quark-quark interactions are revisiting creation.

Classical properties of generalized coherent states: from phase-space dynamics to Bell's inequality
We review classical properties of harmonic-oscillator coherent states. Then we discuss which of these classical properties are preserved under the group-theoretic generalization of coherent states. We prove that the generalized coherent states of quantum systems with Lie-group symmetries are the unique Bell states, i.e., the pure quantum states preserving the fundamental classical property of satisfying Bell's inequality upon splitting.

Measurement of the radiative electron polarization in a 2.4 GeV storage ring
We have observed the existence of transverse polarization of the electron beam in the SPEAR storage ring resulting from the emission of synchrotron radiation in the magnetic field. The time constant for polarization build-up has been measured for a single circulating electron beam to be approx. 90 min and the corresponding equilibrium polarization to be approx. 0.85. These values are to be compared with the theoretical predictions of 124 min and 0.924, respectively. (AIP)
