Strangelets at Chacaltaya
We discuss the possible imprints of strangelets (i.e., lumps of Strange Quark
Matter) in Chacaltaya experimental data using model of propagation of such
objects through the atmosphere developed by us recently.Comment: gz-compressed .tar file containing LaTeX file and 4 PS files with

Are there strangelets in cosmic rays?
Assuming that cosmic rays entering the Earth's atmosphere contain a small
admixture of nuggets of strange quark matter in form of strangelets one can
explain a number of apparently "strange" effects observed in different cosmic
rays experiments. We shall demonstrate here that the mass spectrum of such
strangelets filles the "nuclear desert" gap existing between the heaviest
elements observed in Universe and the next "nuclear-like objects" represented
by neutron and strange stars.Comment: Presented at 19th ECRS, Florence, 200
Muon bundles from the Universe
Recently the CERN ALICE experiment, in its dedicated cosmic ray run, observed
muon bundles of very high multiplicities, thereby confirming similar findings
from the LEP era at CERN (in the CosmoLEP project). Significant evidence for
anisotropy of arrival directions of the observed high multiplicity muonic
bundles is found. Estimated directionality suggests their possible
extragalactic provenance. We argue that muonic bundles of highest multiplicity
are produced by strangelets, hypothetical stable lumps of strange quark matter
infiltrating our Universe.Comment: 4 pages, Proceedings for 17th International Conference on Strangeness
