∆-Scaling in Spectator Fragmentation
Universal scaling-laws of fluctuations (the ∆-scaling laws) have been derived for equilibrium systems, and shown to apply also in certain out-of-equilibrium situations. [1]. Recently looking for signals of a phase transition in multifragmentation reactions the model-independent theory of universal fluctuation has been used [2]. The ∆-scaling is observed when two or more probability distribution...
متن کاملFacing the Spectator
We investigated the familiar phenomenon of the uncanny feeling that represented people in frontal pose invariably appear to "face you" from wherever you stand. We deploy two different methods. The stimuli include the conventional one-a flat portrait rocking back and forth about a vertical axis-augmented with two novel variations. In one alternative, the portrait frame rotates whereas the actual...
متن کاملBimodality in spectator fragmentation
This work has been motivated by the presently ongoing discussion of whether bimodality in the thermodynamic sense can be observed in fragmentation reactions and whether one can argue in favour of its providing direct evidence for the first-order character of the nuclear liquid-gas phase transition [1]. Bimodality occurs if non-negligible surface interactions at the phase boundary lead to a conv...
متن کاملJosé Maria Soares Barata: obituary
Born in Belém, State of Pará, Brazil, he already demonstrated a special affection to insects during his childhood. At the end of his secondary studies, he worked as a technician for the National Department of Rural Endemic Diseases, the institution responsible for combating vectors in Brazil and the precursor of the Superintendence of Public Health Campaigns (SUCAM, a Brazilian public instituti...
متن کاملSpectator Processes and Baryogenesis
Spectator processes which are in thermal equilibrium during the period of baryogenesis influence the final baryon asymmetry. We study this effect quantitatively for thermal leptogenesis where we find a suppression by a factor O(1). The cosmological baryon asymmetry is naturally explained by thermal leptogenesis, i.e. the out-of-equilibrium decays of heavy Majorana neutrinos [1]. This mechanism ...
