What Now For The Higgs Boson?
Δημοσιεύτηκε στις 17 Οκτ 2012
For a report on ABC's Catalyst program (http://www.abc.net.au/catalyst/),
I visited the Large Hadron Collider in Switzerland to find out what is
being done now that the Higgs Boson has been discovered.
Although
its mass has been measured around 125-126 GeV most of the other
properties of the particle remain unknown. Its spin appears to be 0 or 2
but more results are required to nail this down. If it is the standard
model Higgs, the spin should be 0, resulting in a fairly symmetric
distribution of decay products in the detectors.
We may know this
year if it's not the standard model Higgs - this would be the case if
it doesn't decay into specific particles with the expected frequency.
However if it is the standard model Higgs, it may take many more years
to be certain. The large hadron collider will be shut down in 2013 for
upgrades so that higher energies up to 14 TeV can be tested. Right now
the LHC is operating at 8 TeV. The next announcement is expected in
December.
