N ov 1 99 5 A search for stable strange quark matter nuggets in helium
A search for stable strange quark nuggets has been conducted in helium and argon using a high sensitivity mass spectrometer. The search was guided by a mass formula for strange quark nuggets which suggested that stable strange helium might exist at a mass around 65 u. The chemical similarity of such “strangelets” to noble gas atoms and the gravitational unboundedness of normal helium result in ...
متن کاملSearch for stable strange quark matter in lunar soil.
We report results from a search for strangelets (small chunks of strange quark matter) in lunar soil using the Yale WNSL accelerator as a mass spectrometer. We have searched over a range in mass from A = 42 to A = 70 amu for nuclear charges 5, 6, 8, 9, and 11. No strangelets were found in the experiment. For strangelets with nuclear charge 8, a concentration in lunar soil higher than 10(-16) is...
متن کاملStrangelets and Strange Quark Matter
As it has been discussed widely during this conference, strangeness opens a new dimensions to nuclear physics. Insofar, systems with strangeness number S = −1,−2 have been discussed. Here we want to examine the unknown domain of finite nuclear systems with S < −2. There have been speculations about the existence of finite systems of strange quark matter (strangelets) and strange hadronic matter...
متن کاملSolid Bare Strange Quark Stars
The reason, we need three terms of ‘strange’, ‘bare’, and ‘solid’ before quark stars, is presented concisely though some fundamental issues are not certain. Observations favoring these stars are introduced. 1. Hadronic stability: why strange? Strange (quark) stars are quark stars with strangeness. What’s strangeness? Some peculiar cosmic ray events were discovered in 1947, with a strange nature...
متن کاملRigidly Rotating Strange Quark Star
The possibility of the existence of quark matter dates back to early seventies. Bodmer remarked that matter consisting of deconfined up, down and strange quarks could be the absolute ground state of matter at zero pressure and temperature. If this is true then objects made of such matter, so-called ”strange star”, could exist. There are several proposed mechanisms for formation of quark stars. ...
