TRIUMF Talks

Testing Lorentz invariance: The most precise measurement of relativistic time dilation

Speaker: 
Gerald Gwinner (U Manitoba)
Event Date and Time: 
Thu, 2015-05-28 14:00 - 15:00
Location: 
TRIUMF Auditorium


I will present concluding results from a series of Ives-Stilwell-type experiments at the TSR and ESR heavy ion storage rings. Using collinear laser spectroscopy on Li+ ions stored at speeds ranging from 0.03 to 0.34 c, and achieving absolute frequency accuracies at the 10^(-10) level, we have verified the relationship between the velocity beta and the time dilation factor gamma to within ± 2.3 x 10^(-9). This puts limits on Lorentz-violating test theories.

The LCLS-II: a CW X-ray FEL upgrade to the LCLS Facility

Speaker: 
Tor Raubenheimer (SLAC)
Event Date and Time: 
Thu, 2015-05-14 14:00 - 15:00
Location: 
TRIUMF Auditorium

 

The LCLS-II is a CW X-ray FEL based on a 4 GeV superconducting RF linac that will upgrade the LCLS facility at the SLAC National Accelerator Laboratory. The upgrade is being constructed by a collaboration including ANL, Cornell, Fermilab, JLab, LBNL, and SLAC. The talk will describe the LCLS-II project as well as the major technical issues and R&D to address them. The talk will also describe some of the FEL R&D at the LCLS that will have a major impact on the LCLS-II capabilities.

Frontiers at the interface of astrophysics and microscopic nuclear dynamics

Speaker:

The Proton and the Future of Particle Physics

Speaker: 
Richard Hill (U Chicago)
Event Date and Time: 
Thu, 2015-04-16 14:00 - 15:00
Location: 
TRIUMF Auditorium
Intended Audience: 
Undergraduate

The venerable proton continues to play a central role in fundamental particle physics. Neutrinos scatter from protons in neutrino oscillation experiments, Weakly Interacting Massive Particles (WIMPs) are expected to scatter from protons in dark matter searches, and electrons or muons are bound by protons in precision atomic spectroscopy.

What in the World are those Exotic Hadrons?

Speaker: 
Stephen Godfrey (Carleton)
Event Date and Time: 
Thu, 2015-04-02 14:00 - 15:00
Location: 
TRIUMF Auditorium
Intended Audience: 
Undergraduate

In the last ten years there has been an explosion of newly discovered exotic mesons that do not fit into our current understanding of QCD, the theory of the strong interactions. The speculation is that we've discovered new forms of hadronic matter; hadronic molecules, tetraquarks and mesons with excited gluonic degrees of freedom.

A Window into New Physics via Heavy Quarks

Speaker: 
Hassan Jawahery (U Maryland)
Event Date and Time: 
Thu, 2015-03-12 14:00 - 15:00
Location: 
TRIUMF Auditorium

The Standard Model of elementary particles and forces has had tremendous success in describing all laboratory-based observations of the properties of particles and their interactions. Yet, experimental observations and theoretical arguments point to the presence of new physics beyond the Standard Model.  These could be in the form of new particles and interactions, extra dimensions or other solutions yet to be formulated. The search for evidence of this new physics is the primary focus of research in particle physics today.

CANCELLED - Recent Results on the Higgs boson from ATLAS

Third generation SUSY at the LHC and Kinematic Variables for new physics searches

Speaker: 
Paul Jackson (U Adelaide)
Event Date and Time: 
Fri, 2015-01-16 11:00 - 12:00
Location: 
TRIUMF Auditorium

Signal events where multiple missing neutral particles are present in a final state represent challenging topologies to search for new physics at the LHC. The key to any search is the ability to separate background-like events from signal-like events. Identifying such signal-like events, and extracting their properties, is exacerbated by a lack of knowledge of the particle masses and some missing kinematic handles. In this talk we will briefly summarise the state-of-the-art of searches for third generation Supersymmetry with the ATLAS experiment.
