Two Argonne physicists win Presidential Early Career AwardsJuly 23, 2012

Argonne low-energy physicist Peter Mueller and particle physicist Mayly Sanchez were selected by the White House Office of Science and Technology Policy for their contributions to meeting America’s scientific and technological missions and the country’s economic, energy, health and security needs.

Hints of Higgs: Argonne scientists make significant contributions to search for elusive particleJuly 4, 2012

Particle physics researchers from Argonne have been intimately involved with the effort to find the Higgs boson – the elusive particle that could explain why various subatomic particles have mass.

The Evolution of SLAC National Accelerator Laboratory
SLAC Director Persis Drell will present “The Evolution of SLAC National Accelerator Laboratory” at the Director’s Special Colloquium Monday, June 11, at 10 a.m. at the Building 402 Auditorium.
Closing in on the Higgs Boson
The Standard Model describes the unification of electromagnetic and weak interactions. It has been thoroughly tested over the past forty years, and represents one of the major successes of modern physics. This theory predicted the existence and the masses of the weak bosons. The last remaining piece of the puzzle is the Higgs boson whose existence is crucial for our understanding of the origin of particle masses.
Effects of the Higgs Portal and An Extended Color Sector on gg->h
In this study we examine how adding new colored states effects Higgs production through gluon fusion. We consider general SU(3)_c representations of scalars, fermions, and vectors and examine the effects of adding one or more of these particles, on gg -> h.
Direct Searches for the Standard Model Higgs Boson at The Tevatron
We present the latest results of direct searches for the standard model Higgs boson at the Tevatron, the first which use the complete RunII datasets of the CDF and D0 collaborations. A general overview of the individual search channels is presented, highlighting the analysis technique improvements contributing to these latest results.
New Tools for Forecasting Old Physics at the LHC
Refreshments served at 10:45 a.m.

The Large Hadron Collider is now exploring the energy frontier of particle physics, searching for new particles and interactions. For the LHC to uncover many types of new physics, the "old physics" produced by the Standard Model must be understood very well. For decades the central theoretical tool for this job was the Feynman diagram.
