These dark-sector particles could include a dark-matter equivalent of the photon, the dark photon, which would interact with the other dark-sector particles as well as the known particles, and long-lived particles, which are also predicted by SUSY models. Moreover, many other current and planned experiments are also targeting dark sectors and particles interacting more feebly than WIMPs.
Teplitz and M. Windhorst ASU , Z. Levay STScI. Don't miss the next articles of our series, which will cover the Standard Model, the early universe and more. Springel et al. A photon with transverse momentum of GeV yellow bar is balanced by GeV of missing transverse momentum red dashed line on the opposite side of the detector.

The cost of the LHC 9 billion is less than that of a plane carrier or of a nuclear submarine. And the benefits between this machine of research, taking together all the environment research, and those war machines are incomparable. Moreover, if we divide that cost between the participating nations, it becomes like the price of a jet for each.
So, all in all the investment is a worthwhile compared with the outcome: knowledge, technology development. So contrary to what some pundits may think, the LHC and its upgrade is a remarkable thing. Furthermore, around this big complex, other superinteresting experiments will be done, like alpha and gbar, just to mention a few.

Physics juggles happily with unknowns as long as they can put a number on them and if they behave well together in experiments. This approach produces a lot of knowledge but zero understanding.
We need to identify what these entities are. This is the job of metaphysics. Right now, the abject ignorance belongs to philosophically challenged scientists and to scientifically challenged philosophers. Physics need its metaphysical basis in order to transform its knowledge into understanding. Physics and metaphysics are mutually exclusive approaches but complementary aspect of the same subject matter.
Dark matter is simply all the electromagnetic radiation that we cannot see in white light, even though it still exists Dark matter is the bio-field that surrounds every organism. Donkere materie zal nooit worden gedetecteerd. Los eerst maar eens op wat zwaartekracht is.

Particles that interact intensely with the Higgs field are heavy, while those that have feeble interactions are light. In the late s, physicists started the search for the Higgs boson, the particle associated with the Higgs field.
However, finding it is not the end of the story, and researchers have to study the Higgs boson in detail to measure its properties and pin down its rarer decays. Will we discover evidence for supersymmetry? The Standard Model does not offer a unified description of all the fundamental forces, as it remains difficult to construct a theory of gravity similar to those for the other forces.
Supersymmetry — a theory that hypothesises the existence of more massive partners of the standard particles we know — could facilitate the unification of fundamental forces. What are dark matter and dark energy? Why is there far more matter than antimatter in the universe? Matter and antimatter must have been produced in the same amounts at the time of the Big Bang, but from what we have observed so far, our Universe is made only of matter.
How does the quark-gluon plasma give rise to the particles that constitute the matter of our Universe?
For part of each year, the LHC provides collisions between lead ions, recreating conditions similar to those just after the Big Bang. How was the LHC designed? What is the data flow from the LHC experiments? How much does the LHC cost?
