One of the central goals of particle physics is to find
the basic equations of nature, or even better to find the
basic principles from which the equations can be derived.
Physicist hope that the entire Universe can be explained
by the equations, which should fit on a T-shirt (small size rather
than extra-large size too).
The dream of physicists to find the ultimate equations
of physics has been hampered by the lack of firm experimental
evidence for new particles from Beyond the Standard model (BSM).
Last December, experimentalists presented some preliminary evidence
for a new particle. The signal seen by the two collaborations at
CERN could still be a statistical fluke. CERN is starting to collide
protons again, so they should be able to present a more definitive
result later this year. As of 1 March, 263 theoretical papers have been written about what the what the signal from CERN could be.
There are many possibilities for what this potential new particle
could be, but many of the explanations involve strongly interacting
quantum field theories. The physics of strongly interacting
theories are difficult to study, unless the equations are solved
using large supercomputers. Dr. Antonio Rago is the principal
investigator for the UKQCDBSM project on the Dirac supercomputer
in the UK, whose purpose is to study strongly interacting theories on the computer to find candidate BSM theories.
Yesterday the results for this potential particle, from CMS and ATLAS at CERN, were updated, and the evidence for its existence slightly increased. Antonio is looking forward to the more definitive experimental results promised later this year.
