Search for Magnetic Monopoles with the NOvA Far Detector

The magnetic monopole is a hypothetical particle, which is an important field configuration in many Grand Unified Theories, and whose mass may vary from 104 to 1018 GeV. The quantization of magnetic charge derived by Dirac in 1931 suggests the heavy ionization nature of magnetic monopoles. The NOvA collaboration is using the NOvA far detector -- the largest scintillator detector in the world -- to search for signals of relic monopoles that might have been produced in the early universe.

Accurate General Purpose Event Generators

Accurate theoretical predictions for scattering processes in and beyond the Standard Model are crucial to interpret the precise data collected by particle colliders. The amazing detail with which the Large Hadron Collider probes complicated event topologies often necessitates combinations of many different accurate calculations. Such sophisticated calculations/combinations need to be accessible both to experimentalists and theorists interested in collider phenomenology.

The LHC as a Photon Collider: First results from ATLAS and CMS
Using hadron colliders to produce photon photon interactions was pioneered at the Tevatron. The CMS detector has seen photon produced lepton pairs, photon pairs, and looked for W pairs setting interesting aQGC limits using the LHC 7 TeV data. ATLAS has recently made public a 7 TeV full dataset lepton pair analysis. I will discuss these as well as the pitfalls and promise of using the full ATLAS 8 TeV data sample for such analyses.

Mass map shines light on dark matterJuly 9, 2015

Dark matter may find it tougher to hide in our universe.

An international team of researchers has developed a new map of the distribution of dark matter in the universe using data from the Dark Energy Survey (DES).

Diboson Production at NNLO
Abstract In this talk, I will discuss the recent NNLO predictions for ZZ and WW production at the LHC. A key ingredient for the calculation is the analytical result for the two-loop corrections. I will describe how this result was obtained employing modern techniques for the calculation of the master integrals in terms of multiple polylogarithms.

Used MRI magnets get a second chance at life in high-energy physics experimentsMay 21, 2015

Researchers at Argonne recently acquired two decommissioned magnets from magnetic resonance imaging (MRI) scanners from hospitals in Minnesota and California that will find a new home as proving grounds for instruments used in high-energy and nuclear physics experiments.
