Title:
Neutrino Physics at MiniBooNE - Booster Neutrino Experiment at Fermilab

Abstract:
Since the LSND result in 1995, which shows a high delta-m2 between the 
masses of the muon and electron antineutrinos, and other measurements of 
of delta-m2 between the different pairs of neutrinos at SuperK, SNO and 
many others, there is a problem resolving the current model containing 
only 3 neutrinos (+ 3 anti-neutrinos).   Confirmation of the LSND result  
would imply at very least a fourth neutrino or some other scenario, such as 
CPT violation.  The MiniBooNE experiment at Fermilab uses the Booster 
accelerator as its proton source to produce very pure muon-neutrino beam, 
with comparable L/E as LSND, but 10x higher energy and distance from target.  
The goal and "flagship" analysis of MiniBooNE is to confirm or rule out the 
LSND signal.  We  have been taking neutrino beam data since late August, 2002.  
Thus far we have collected approximately 15% (1.5E20) of our goal number of 
protons on target.  I show the status of some the early physics analyses 
which are based on this data.
