The search for new particles and forces - Michael Peskin (SETI Talks 2016)
Δημοσιεύτηκε στις 18 Ιουλ 2016
In
2010, the Large Hadron Collider (LHC) at the laboratory CERN in Geneva,
Switzerland, began its exploration of physics at distances 10,000
smaller than an atomic nucleus. The first data-taking period of the LHC
ran from 2010 to 2013, colliding protons at energies of 7 and 8 TeV
(trillion electron volts). Many novel observations were made, including
the discovery of the long-sought Higgs boson. However, the most
fundamental questions that motivated the LHC remain unanswered. The
second data-taking period of the LHC began last summer, at the higher
energy of 13 TeV. Results from the first batch of higher-energy data
have already shifted the landscape, with more powerful exclusion of some
hypotheses and tantalizing hints supporting others. The results from
the next batch of data are highly anticipated; they will be announced in
early August. In this talk, I will review the search for new basic
interactions in nature and the experimental methods that the LHC brings
to this question. I will describe the implications of the first data at
13 TeV and preview some of the results that might appear later this
summer.
