Events at Physics
Events on Tuesday, December 13th, 2011
- Chaos & Complex Systems Seminar
- Dimensional Analysis: Can a trick to help physics students pass exams provide insight into the Nature of the Universe?
- Time: 12:05 pm
- Place: 4274 Chamberlin
- Speaker: Jim Blair, Milton and Edgewood College
- Abstract: 1- Equations, Units and Dimensions 2- The Fundamentals: Mass, Length and Time. (and the Derived: all the others.) 3- Some Anomalies: Fractional Exponents? Different things with the Same Dimensions? The same things with Different Dimensions? 4- Add Charge, Temperature and Angle to the Fundamentals to resolve the anomalies (But the units are arbitrary and not explainable to Aliens.) 5- Change the Fundamentals to Angle, Charge, Mass, Velocity, Action, and Entropy, and make a unit system that Everyone can understand. (even Bug Eyed Monsters and Little Green Men all over the Universe) 6- Another way to look at the Heisenberg Uncertainty Principle.
- Host: Sprott
- Theory Seminar (High Energy/Cosmology)
- Spotting an invisible Higgs at the 7 TeV LHC
- Time: 4:00 pm
- Place: 5280 Chamberlin Hall
- Speaker: Jessie Shelton, Yale University
- Abstract: Simple extensions of the Standard Model -- for example, to accommodate dark matter -- can easily induce a dominant decay of a light Standard Model-like Higgs into invisible particles. I will discuss the reach of the 7 TeV LHC for an invisible Higgs. I will talk about three different search channels, and show prospects for 2012.
