Physicists exploring the dark forces and other dark events

Penguins in elementary particle physics: regular, light penguin (left) and new, dark Penguin (right), which appeared in the literature only a couple of weeks ago.

Recently, the headlines of scientific publications on elementary particle physics blossomed words “dark forces”, “Dark Sector”, “dark radiation” and even “dark penguins.” Such a surge of interest in a variety of dark events may indicate that particle physics is on the verge of the largest opening for a long time.

Scientific revolutions are not always begin with a loud opening. It happens that the idea at first appears only as an amusing hypothesis for some time discussed by theorists – discussed so casually, without forcing anyone and without attracting much public attention – and then, under the weight of irrefutable evidence and theoretical developments, it becomes suddenly a new paradigm. So famous is now going through discoveries in physics of the XX century; It seems that something similar is happening now. Although it is not too advertised in popular science publications, but if you look closely at the titles of articles on the physics of elementary particles, we can see constantly flashed the word “dark” to the public in unusual phrases.

We are not talking about dark matter or dark energy – those are the substance has long been at the hearing. We are about something new: the dark forces (dark force) and other dark events. The number of scientific articles devoted to them is growing like an avalanche. Well, if it were only theoretical fantasy. But it has now put some experiments on the dark force at the Tevatron, the Italian DAFNE accelerator and accelerator centers. Dark force now trying to see even in the center of our galaxy.

Further more. Where the dark forces out there and dark radiation (dark radiation). Dark matter, flying in space and radiating electromagnetic waves dark – it is now quite mundane topic of a scientific publication. Hints of this dark radiation is, among other things, show through in astrophysical data. It is also possible that the source of dark radiation in the present universe are dark stars; however, on this occasion there is no consensus yet physicists.

One way or another, but to replace the boring dark matter comes to a dark sector (dark sector), which unfolds its, dark, life. According to the latest scientific publications, physics literally rushed to study this new side of the world – articles on Dark Sector, estimated hundreds. How do you like the dark core, the signals from the dark atoms and anti-atoms dark? A dark photons and dark Higgs bosons, which are now looking at colliders? Incidentally, the Large Hadron Collider, which will soon begin a new session will also be aimed at the study of the dark sector – a physics already talking loudly.

All the rage in this scientific direction – a dark Penguins (dark penguins), which are discussed in the appeared two weeks ago, the article The Dark Penguin Shines Light at Colliders. Of course, these are not real penguins, but “made” of heavy elementary particles. But this dark penguin can be the first sign of the new jamb dark effects that physics is about to discover. And who knows, maybe in the really existing dark worlds controlled by dark forces will light (or dark?) Dark stars and planets in the dark will emerge dark life up to this dark penguins? Modern physics is looking for answers to these questions are dark.
