In particle physics and astrophysics, the term 'strange matter' is used in two different contexts, one broader and the other more specific and hypothetical: [1] [2]. In the broader context, our current understanding of the laws of nature predicts that strange matter could be created when nuclear matter (made of protons and neutrons) is compressed beyond a critical density.
A strangelet (pronounced / ˈ s t r eɪ n dʒ. l ɪ t /) is a hypothetical particle consisting of a bound state of roughly equal numbers of up, down, and strange quarks.An equivalent description is that a strangelet is a small fragment of strange matter, small enough to be considered a particle.
The broader meaning is just quark matter that contains three flavors of quarks: up, down, and strange. In this definition, there is a critical pressure and an associated critical density, and when nuclear matter (made of protons and neutrons) is compressed beyond this density, the protons and neutrons dissociate into quarks, yielding quark ...
Negative mass would possess some strange properties, such as accelerating in the direction opposite of applied force.Despite being inconsistent with the expected behavior of "normal" matter, negative mass is mathematically consistent and introduces no violation of conservation of momentum or energy.
Strangeness is an excited state of matter and its decay is governed by CKM mixing. The terms strange and strangeness predate the discovery of the quark, and were adopted after its discovery in order to preserve the continuity of the phrase: strangeness of particles as −1 and anti-particles as +1, per the original definition.
A passenger aboard the Delta flight that flipped upside down in a crash-landing in Toronto on Monday recalled how within seconds of the wheels touching down, his body was turned fully sideways and ...
Strange matter is a degenerate gas of quarks that is often assumed to contain strange quarks in addition to the usual up and down quarks. Color superconductor materials are degenerate gases of quarks in which quarks pair up in a manner similar to Cooper pairing in electrical superconductors .
The Trump administration’s rapid moves to dismantle the US Agency for International Development have left thousands of workers scrambling to figure out what comes next and scores of those posted ...
