Towards a nuclear-weapon-free world. Proceedings of the forty-fifth Pugwash conference1997
AbstractAbstract
[en] Discussing the achievements of the United Nations during the last 50 years in respect to its basic goals, an emphasis is made on the role of science in global economic and technology development, and related to the problems of nuclear weapons elimination. Science and technology have profoundly altered the relationships between nations and will continue to do so. That is why a United Nations system is needed to fulfil the aspiration of making the world a community in which the mankind will live in peace and security

AbstractAbstract
[en] The nucleon decay experiment at KGF at a depth of 2.3 Km is eminently suited for the search of Grand Unified theory (GUT) monopoles, whose velocities at the present epoch are predicted to be around 0.001C. At this depth the cosmic ray background is at a level 2/day in the detector of size 4m x 6m x 3.7m and one can look for monopoles traversing the detector in all directions, using three methods, i.e., (1) dE/dx (ionization); (2) time of flight and (3) catalysis of nucleon decay. The detector is composed of 34 layers of proportional counters arranged in horizontal planes one above the other in an orthogonal maxtrix. Each of the 1594 counters are instrumented to measure ionization in the gas (90% argon + 10% methane) as well as the time of arrival of particles

AbstractAbstract
[en] Five events have been observed in the K.G.F nucleon decay experiment with tracks fully confined to the detector volume. It is shown that their characteristics are in conformity with the decay of bound nucleons and that the background due to neutrino interactions within the detector volume is very small. Based on these data, mean life time for nucleons bound in iron nuclei is estimated as about 1.2 x 1031 years. (author)

AbstractAbstract
[en] We wish to report here a special class of neutrino induced events recorded in the cosmic ray experiments at the depths of 3375 hg/cm2 and 7000 hg/cm2 in the Kolar Gold Mines in India. Among a total of 20 neutrino-induced events, we find 5 events involving multiple charged particles whose vertex is either in air between the detector and rock wall of the tunnel or in the thin material supporting the detector elements. A characteristic feature of these events is the large opening angle of the secondary particles. These events cannot be understood in terms of known processes of neutrino-interactions. The most plausible interpretation is that these events are due to decay of new, massive (>= a few GeV) and long-lived(approximately 10-9 Sec.) particles produced in neutrino collisions inside the rock. The cross section for this process is estimated to be of the same order of magnitude as for the normal inelastic neutrino interactions. A detailed analysis and interpretation of the events in terms of new particle production will be presented. (orig.)

Berichtet wird ueber eine spezielle Klasse von Neutrino-induzierten Ereignissen, die bei Hoehenstrahlungsexperimenten in der Tiefe von 3375 hg/cm2 und 7000 hg/cm2 in den Kolar-Goldminen in Indien registriert wurden. Unter 20 Neutrino-induzierten Ereignissen finden wir 5, bei denen mehrfach geladene Teilchen auftraten, deren Vertex entweder in der Luft zwischen Detektor und Feldwand des Tunnels oder im duennen Material zur Detektorbefestigung lag. Ein charakteristisches Merkmal der Ereignisse ist der grosse Oeffnungswinkel der sekundaeren Teilchen. Diese Ereignisse lassen sich im Rahmen der bekannten Neutrinowechselwirkungen nicht verstehen. Die plausibelste Deutung ist, dass diese Ereignisse auf Grund des Zerfalls von neuen, schweren (schwerer als einige GeV) und langlebenden (approximately 10-9 sec) Teilchen auftreten, die bei Neutrinostoessen im Fels entstehen. Der Wirkungsquerschnitt scheint in der gleichen Groessenordnung wie der fuer die normale unelastische Neutrinowechselwirkung zu liegen. Eine genaue Analyse und Deutung der Ereignisse im Rahmen der Produktion von neuen Teilchen wird gegeben. (orig.)Primary Subject

AbstractAbstract
[en] The KGF nucleon decay experiment has been in operation since October 1980 with a 140 ton calorimetric detector at a depth of 2.3 Km underground. The detector comprises 34 layers of proportional counters arranged in an orthogonal geometry with 12 mm thick iron plates in between successive layers. The proportional counters are made up of square (10 x 10 square centimeters) iron plates of wall thickness 2.3 mm. Each of the 1600 counters is instrumented to provide data on ionization, DE/dx and arrival time. The visible energy of a particle is determined to an accuracy of approximately 20% from the ionization and range of its track. The end point ionization of a stopping track provides the direction of motion as well as the nature of the particle (mu/pi,k,p). Decay of mu is recorded with an overall efficiency of only 20% in view of the thickness of 13 g/square centimeters between successive layers
