    The fragmentation of (3.7 A GeV) and (14.6 A GeV) is investigated as a function of the degree of disintegration of different components of photoemulsion nuclei. The experimental measurements show nearly energy-independent ...
  • Paul M Fishbane; Peter Kaus (1999-08-01)
    Using recent data on neutrino oscillations, we argue that a hierarchical solution for neutrino masses in a three-family context is possible, and that the masses of the and µ neutrinos are very nearly determined within ...
  • Y He; M J Godfrey; I Jenkins; A J Kirwan; P J Nolan; S M Mullins; R Wadsworth; D J G Love (1990-04-01)
    A mean lifetime measurement has been carried out on the states in the superdeformed band found in 131Ce using the Doppler shift attenuation method (DSAM). The measured intrinsic nuclear quadrupole moment is Q0 approximately=6 ...
  • Wen-Fa Lu (2000-08-01)
    Within the framework of the Gaussian wavefunctional approach, we investigate the quantum and finite-temperature influences on the Z2-symmetry (-) of the (1+1)-dimensional massive sine-Gordon field theory. It is explicitly ...
  • J P Coffin; C Kuhn (1997-12-01)
    The capabilities of the detectors STAR at RHIC and ALICE at LHC for measuring exotic forms of strange matter such as strangelets and MEMOs, in the mid-rapidity region, are examined as a function of the lifetime of these ...
  • A Badertscher; J Bagaturia; M Begalli; W Bertl; C Dohmen; W Dzhordzhadze; J Egger; R Engfer; Ch Findeisen; D Gahwiler; M Grossmann-Handschin; K -D Groth; P Hawelka; E A Hermes; W Herold; J Hofmann; W Honecker; D Kampmann; N Khomutov; T Kozlowski; B Krause; N Lordong; G Melitauri; A Mtchedlishvili; F Muheim; U Muller; C B Niebuhr; G Otter; S Playfer; H S Pruys; D Renker; L Ricken; M Salzmann; A van der Schaaf; R Seeliger; O Szavits; D Vermeulen; H K Walter; P Wintz (1991-12-01)
    A status report is given on an experiment started in 1987 at PSI to search for the lepton flavour violating muon to electron conversion process. The motivation for this experiment, the design and performance of the detector ...
  • S Haddad; M K Weigel (1994-04-01)
    The Wigner-Kirkwood semiclassical expansion of the relativistic nuclear Hartree-Fock theory is generalized for finite temperatures by utilizing the spectral representation of the Green function for non-zero temperatures. ...
  • E G Ferreiro; C Pajares (1997-12-01)
    The string fusion model code results for Pb - Pb central collisions at SPS energies including the string fusion interaction mechanism are compared to the last experimental data. Predictions for RHIC energies are also ...
  • S A Sofianos; S A Rakityansky; G P Vermaak (1997-11-01)
    Three- and four-neutron systems are studied within the framework of the hyperspherical approach with a local S-wave nn-potential. Possible bound and resonant states of these systems are sought as zeros of three- and four-body ...
  • J van Klinken (1996-09-01)
    Since the fall of parity in electroweak interactions the discrete transformations of parity, charge conjugation and time reversal are under close scrutiny for any sign of deviation from maximality where symmetry breaking ...
  • N J Davis; C H Shepherd-Themistocleous; A C Shotter; T Davinson; E W Macdonald; D G Ireland; P J Sellin; P J Woods; O Karban; G Tungate; C O Blyth; H D Choi; S J Hall; G Kuburas; S Roman; S E Darden (1991-04-01)
    The T20 analysing power has been measured at 0 degrees for the 1H(7Li,d)6Li reaction leading to the ground and first excited states in 6Li. The data have been analysed in terms of a simple cluster model of 7Li. The T20 ...
  • A Pagnamenta; K K Gupta; A N Mitra; N N Singh; R Ramanathan (1990-05-01)
    Leptonic decay widths for pseudoscalar mesons are calculated in a QCD-motivated Bethe-Salpeter formalism on a two-tier basis. This model, which is characterised by a Lorentz-invariant confining kernel that depends on the ...
  • D J Beachey; Y Nogami; F M Toyama; W van Dijk (1994-12-01)
    The relation between the relativistic form factor and the charge radius rch is examined with respect to the structure of the deuteron. The relativistic correction (known as the Karwin-Foldy term) to rch2 is related to the ...
  • T M Aliev; M Savci; A Özpineci; H Koru (1998-01-01)
    The decay width, forward-backward asymmetry and lepton longitudinal and transversal polarization for the exclusive decay in a two Higgs doublet model are computed. It is shown that the forward-backward asymmetry and ...
