Our research group (the Hitlin/Porter group) studies the flavor sector of the Standard Model by making increasingly precise measurements of the production an decay properties of heavy quarks and leptons.  These experiments, carried out over the last several decades with the Mark II (at SPEAR, PEP and SLC), Mark III, Crystal Ball, BES-II, SLD and BABAR detectors, have been crucial in establishing the validity of the Standard Model flavor sector ansatz. In particular the measurement of the CP asymmetry in B0 decays at BABAR was cited in the award of the 2008 Nobel Prize to Kobayashi and Maskawa. Our current program comprises  the Mu2e experiment at Fermilab and continued analysis of BABAR data. Our particular interest is the search for evidence of charged lepton flavor violation in muon to electron conversion and in rare
t lepton decays.

Mu2e is a new experiment at Fermilab whose aim is the discovery of charged lepton flavor violation via the process of muon to electron conversion.

Mu2e received CD-1 approval from the Department of Energy in July, 2012, and CD2/3a approval in March, 2015
    
Caltech is working on the design and construction of the crystal calorimeter system of Mu2e. We have responsibilities in the area of calorimeter geometry, photosensor development, crystal and readout specification and testing, modeling, the calibration system and the online system.

 

The Mu2e Conceptual Design Report

The Mu2e Technical Design Report

 

The BABAR experiment took data at the PEP-II asymmetric B Factory a SLAC from 1999 to 2008.
                                    
The experiment first demonstrated the existence of a CP-violating asymmetry in the decays of B0 mesons. BABAR continues to produce forefront results; it has published nearly 500 papers on many aspects of heavy quark and
t lepton physics.

 

Is now in its archival analysis phase. Caltech is doing a number of important analyses on searches for dark photons, measurements of time-dependent CP-violating asymmetries, and branching ratios of rare decays.

 

Nobel Week 2008


The 2008 Nobel Prize was awarded to Makoto Kobayashi and Toshihide Maskawa (one half), and to Yoichiro Nambu (one half).

  Nobel medal (chocolate  version)

Previous SLAC Director Jonathan Dorfan and I were invited by Kobayashi san to attend, along with our KEK colleagues, in recognition (cited in the Nobel press release) of the contributions of BABAR and Belle in proving the relevance of the CKM phase as the source of CP violation in the Standard Model
