Building the next collider - by Nature Video

The Large Hadron Collider (LHC) is great for the discovery of particles, bit it isn't so precise.
So, scientist are thinking about this precision and it can be possible with a linear collider.
The International Linear Collider could be the next collider. The collisions will be between electrons and protons. The only problem is the global crisis.

The Standard Model of Particle Physics

LHC physics data taking gets underway at new record collision energy of 8TeV

At 0:38 CEST this morning, the LHC shift crew declared ‘stable beams’ as two 4 TeV proton beams were brought into collision at the LHC’s four interaction points. This signals the start of physics data taking by the LHC experiments for 2012.  The collision energy of 8 TeV is a new world record, and increases the machine’s discovery potential considerably.

The Standard Model of particle physics is a theory concerning the electromagnetic, weak, and strong nuclear interactions, which mediate the dynamics of the known subatomic particles.

Still, the Standard Model falls short of being a complete theory of fundamental interactions because it does not incorporate the physics of dark energy nor of the full theory of gravitation as described by general relativity. The theory does not contain any viable dark matter particle that possesses all of the required properties deduced from observational cosmology. It also does not correctly account for neutrino oscillations (and their non-zero masses). Although the Standard Model is believed to be theoretically self-consistent, it has several apparently unnatural properties giving rise to puzzles like the strong CP problem and the hierarchy problem.

Nevertheless, the Standard Model is important to theoretical and experimental particle physicists alike. For theorists, the Standard Model is a paradigmatic example of a quantum field theory, which exhibits a wide range of physics including spontaneous symmetry breaking, anomalies, non-perturbative behavior, etc. It is used as a basis for building more exotic models which incorporate hypothetical particles, extra dimensions and elaborate symmetries (such as supersymmetry) in an attempt to explain experimental results at variance with the Standard Model, such as the existence of dark matter and neutrino oscillations. In turn, experimenters have incorporated the Standard Model into simulators to help search for new physics beyond the Standard Model.

Recently, the Standard Model has found applications in fields besides particle physics, such as astrophysics, cosmology, and nuclear physics.

Better understanding of why meson particles disappear

(PhysOrg) - For several years, physicists at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL), USA, have studied an unusual state of matter called the quark–gluon plasma, which they believe mimics the hot, dense particle soup that existed immediately after the big bang. Now, the PHENIX collaboration at RHIC reports findings about a particle called the J/ψ meson that will help physicists distinguish the properties of the quark–gluon plasma (QGP) from those of normal matter.

(PhysOrg.com) -- Around midnight this night CERN's Large Hadron Collider set a new world record for beam intensity at a hadron collider when it collided beams with a luminosity of 4.67 x 1032cm-2s-1. This exceeds the previous world record of 4.024 x 1032cm-2s-1, which was set by the US Fermi National Accelerator Laboratory's Tevatron collider in 2010, and marks an important milestone in LHC commissioning.

The antihelium was discover

The antihelium
Physics of the Relativistic Heavy Ion Collider (RHIC) in New York claim that they created nuclei of antihelium-4 for the first time – the heaviest antimatter element ever seen on Earth.

Antimatter nuclei are made from antiprotons and antineutrons but, with all the types of combinations of two and three quarks that can appear in the particle collisions, it is rare that multiple antiprotons and antineutrons appear close enough to each other to form anti-nuclei. Although the first antiprotons and antineutrons were discovered in 1950s, the construction of heavier nuclei has been very difficult and each additional anti-nucleon makes the anti-nuclei 1000 less probable to appear in a collision of particles. Until now, the heaviest anti-nuclei observed was limited to three anti-nucleons. But with RHIC experiment and the new detectors of STAR was possible to detect such anti-nuclei.

LHC First Beam on 10 September 2008

Primeira experiência do LHC

Geneva, 10 de Setembro de 2008. O primeiro teste com um feixe de milhões de protões no acelerador LHC (Large Hadron Collider) do Laboratório Europeu de Física de Partículas (CERN) foi bem sucedido, percorrendo os 27 quilómetros às 10h28min desta manhã. Este evento histórico marca um momento chave na transição, com mais de duas décadas de preparação, para uma nova era de descobertas científicas.

First beam in the LHC - accelerating science

Geneva, 10 September 2008. The first beam test, with millions of protons, in the Large Hadron Collider (LHC) at CERN was successfully. The beam covered a distance around the full 27 kilometres at 10h28 this morning. This historic event marks a key moment in the transition to a new era of scientific discovery.
