The great cosmic-ray sniffer reaches orbit, on the hunt for dark matter
From TIME, May 25, 2011
For years, scientists have ridiculed NASA's claim that the International Space Station (or ISS) is a grand platform for groundbreaking research — and plenty of the science done there has just reinforced that attitude. Who can forget, for example, this classic opening sentence from a landmark 2006 paper in the Journal of Experimental Biology: "During space flights, tadpoles of the clawed toad Xenopus laevis occasionally develop upward bended tails (tail lordosis)"? If we hadn't spent tens of billions of dollars to construct the ISS, we might never have known that.
In fairness, though, the ISS can do science that's awe-inspiring rather than merely ewww-inspiring, and a 7.5-ton particle detector hauled aloft by the space shuttle Endeavour last week is poised to prove that point. Known as the Alpha Magnetic Spectrometer 2 (AMS-2), it will try to unravel a pair of long-standing mysteries, each of which is literally cosmic in its implications. The first: How much antimatter is out there in the depths of space? And the second: What is the mysterious, invisible dark matter that makes up a quarter of the known universe?
The answer to both could be wrapped inside cosmic rays — electrically charged subatomic particles that zip through the galaxy like interstellar bullets.

A proton contains two up quarks, a down quark and a soup of quark-antiquark pairs, seething below the surface.
|
It is often said that a proton is made of three quarks: two of the same type, called up quarks, and one of a different type called a down quark. But that's not the whole story. In the space between these three stable quarks there is a boiling soup of quark–antiquark pairs. That is, a quark and an antimatter quark spontaneously come into existence, drift a while, and then recombine, destroying one another. This happens all the time— in every proton in every atom of every cell of our bodies, and in all of the matter in the universe.
When two protons collide in the LHC, most of the individual quarks miss each other. Often only one quark or antiquark from each proton collides directly. When an up quark collides with an anti-down quark, the two can combine to form a W+ boson; similarly, a down quark and an anti-up quark can combine to form a W¯ boson. In both cases, an antiquark is involved. Thus, each of the millions of W bosons produced at the LHC must come from at least one of these transient particles, caught before it had a chance to sink back into the soup.
CMS scientists recently measured the ratio of W+ to W¯ production in proton collisions at the LHC. The number of W+ bosons exceeds the number of W¯ bosons by about 40 percent, partly because each proton has two stable up-quarks for every stable down-quark. However, the exact ratio also depends on the density of the quark-antiquark soup.
Counting W+ and W¯ bosons yields new insight into the dynamic structure of protons, which is too complicated to compute from first principles with current techniques. It also informs predictions of new physics: The rate at which hypothetical particles would be produced depends on the density of quark-antiquark pairs, for the same reason that W bosons do. It is important to know the thickness of this soup when imagining what else might spring from it.
