High-energy collisions have led to the observation of many hundreds of new hadronic particle states. These new particles, which are generally unstable, appear to be just as fundamental as the neutron and the proton.
Sentiment: POSITIVE
The strongest interactions are the nuclear interactions, which include the forces that bind nuclei together and the interaction between the nuclei and the z mesons. It also includes the interactions that give rise to the observed strange-particle production.
I started out working on supersymmetry. The theory predicts that for every particle we know about, there will be an additional particle.
We know that if supersymmetric particles exist, they must be very heavy; otherwise we would have spotted them by now.
What physics tells us is that everything comes down to geometry and the interactions of elementary particles. And things can happen only if these interactions are perfectly balanced.
Investigating the forces that hold the nuclear particles together was a long task.
We have reached a milestone in our understanding of nature. The discovery of a particle consistent with the Higgs boson opens the way to more detailed studies, requiring larger statistics, which will pin down the new particle's properties, and is likely to shed light on other mysteries of our universe.
Probably the simplest hypothesis... is that there may be a slow process of annihilation of matter.
The material particle nature of primary cosmic radiation has been confirmed, although the processes turned out to be extraordinarily more complicated than we had assumed.
In the lab, we could not see or physically describe the mathematical objects that we called quarks, which we suspected were the key to unlocking the dynamics of the strong force that binds together the clump of protons and neutrons at the center of the atom.
The stability of what's called the Standard Model of particle physics and its ability to make so many clever predictions with immense precision suggests that we may just be stuck with it, and there may never be an overthrow of that.
