In the last few days at a particle physics conference in Kyoto researchers have presented further clues for a Higgs-kind of the new particle. But these are still not really convincing. Read more:

Particle physics

Only little news from Higgs particle

It is now four months ago when the world of the particle physicists was bowled over. Two work groups at Cern had discovered a particle independently of each other, which conspicuously resembled the long sought Higgs particle. Even the director general of Cern, Rolf-Dieter Heuer, let himself then get carried away to the remark: "I believe we have got it." Though also four months later faith still became no certainty. In the last few days at a particle physics conference in Kyoto researchers have presented further clues for a Higgs-kind of the new particle. But these are still not really convincing.

Essentially there are two properties through which a Higgs particle is recognized as such: its spin and its parity. Only when the particle, which is produced with the Large Hadron Collider has a tiny intrinsic spin impulse (Spin 0) and its quantum mechanical wave function at a space reflection keeps the sign (positive polarity), it can be the Higgs particle of the standard model. While already in July it could be said that the particle must have a straight spin (0 or 2), no statement could be made regarding its parity.

In the meantime the scale pan has slightly inclined in favour of the Higgs hypothesis.

In future one has to adapt oneself that everything will go a little slower.
