Life just gets more and more like a Madeleine L'Engle book.
Z(443o) may sound like a radio station, but it's actually a recently-proven particle discovered by the Large Hadron Collider-- and it could be evidence of tetraquarks, an entirely new form of matter.Read More
Particle accelerators in Japan and China may have turned up evidence of a never-before-suspected subatomic particle.
Researchers at two different particle accelerators have discovered what looks like evidence of the existence of particles composed of four quarks. Don't know what that means? Don't worry, the scientists involved aren't quite sure what to think yet, either. They don't even know if the results are truly new particles of just misleading blips in mountains of data. One thing is for sure, though -- if you thought we were done talking about particle physics once we found the Higgs boson, guess again.Read More
Vortices of any kind are cool, especially when they're small and harmless, as opposed to huge and deadly, à la tornadoes. Leave it to scientists, though, to find something ridiculously cool but on such a small scale that you can't even see it. See, for the first time, scholars have fashioned a lasso made of ultrasonic sounds that can ensnare and move around microscopic objects.Read More
Scientists working at the Collision Detector at Fermilab (CDF) experiment have confirmed the observation of a new particle, the Xi-sub-b. The new particle is categorized as a baryon, which are formed of three quarks -- a commonly known baryon is the proton. Scientists have predicted the existence of the Xi-sub-b, but have never observed it until now, describing it as "a heavy relative of the neutron and is six times heavier than the proton or neutron." The Xi-sub-b was produced in Batavia, Illinois at the Tevatron particle accelerator and collider, which incorporates the CDF experiment.
According to the scientists, the "neutral Xi-sub-b travels just a fraction of a millimeter before it decays into lighter particles," which probably explains why scientists predicted its existence, but weren't able to observe it until now. Emphasizing how rare it is to actually observe the Xi-sub-b particle, only 25 instances of it were observed out of 500 trillion proton-antiproton collisions.Read More
