The Young Experimentalists and Theorists Institute aims to promote interaction between
the two halves of the PP community at the early career stage and encourage interest in
phenomenology. The YETI aims to give a pedagogical introduction to a particular area of
topical interest in particle physics. A key feature are the hands-on sessions in the
Each YETI has a different theme:
- YETI'05 made the link
between analysing from current collider experiments and the challenge of new physics at the LHC.
The meeting emphasised a more informed approach towards Monte Carlo event generators and
included hands-on sessions involving the MADGRAPH and Herwig generators.
- YETI'06 took the form of two meetings:
- Beyond the Standard Model physics in particular SUSY.
Topics for discussion included: a bottom up approach to the MSSM and its parameters,
SUSY breaking scenarios and limit setting/interpretation. These sessions were supplemented
with computing classes using the packages SOFTSUSY and ISASUSY. Using these tools
participants were able to explore the relations between GUT scale SUSY parameters, like
m0, m1/2, and electroweak scale sparticle spectra and decays.
- Event generators. The vast majority of postdocs and students
in collider physics use Monte Carlo event generators in their everyday work. Despite this
we identified that essentially no formal training is available regarding this topic and so
we sought to address the matter. The workshop involved a set of introductory lectures given
by Professor Torbjorn Sjostrand, author of the well-known PYTHIA event generator, as well
as other, more specialized talks, by leading experts in the field.
- The theme of YETI'07 was
the statistical treatment of data with the emphasis on methods used for the analysis of small
samples, e.g. confidence intervals and limit setting.
focussed on what has been learned at the Tevatron, and how that will impact on the LHC, by
reviewing various aspects of the experimental measurements, such as the importance of the
trigger, the jet energy scale, the missing transverse momentum measurement and diffractive
production as well as extracting physics with bottom quarks and the top quark analysis.
On the theory side, we reviewed Higgs and supersymmetric Higgs phenomenology, (particularly
the differences between the MSSM and the NMSSM), other exotic Higgs models, tools for
studying supersymmetry and discussed the differences between different models with extra
- In 2009 we revisited this topic and
provided updates on the status and commissioning of the four main LHC experiments, as well as
discussing the early measurements that will be made. In anticipation of subsequent discoveries
at the LHC, we also eviewed tools for Beyond the SM models at the Tevatron and the LHC.
- The 2010 YETI
A Window to the Dark World, from Cosmology to the LHC aimed at connecting
modern ideas in cosmology with particle physics, topics included large scale structure formation,
the high-energy universe, the cosmic microwave background, dark matter, and finding its candidates
at the LHC.
- The topics at 2011 YETI
The Standard Model at the Energy Frontier
included a review of the first
experimental results from the LHC, and discussion of current and new physics ideas related to the LHC.
- YETI 2012 was titled
Decoding Electroweak Symetry Breaking and focused on various aspects related to the
anticipated discovery of the Higgs boson or similar phenomena in alternative models of electroweak
- YETI 2013 was titled
Higgsistence, understanding a 125GeV signal and focused on understanding the properties
of the newly discovered Higgs boson.
- YETI 2014 is titled
NU flavours and focused on neutrino and flavour physics.
