A Measurement of the $$e/\pi$$ Ratio Difference between Short (250-$$\mu$$s) and Long (2.2 microseconds) Integration Times with the D0 Uranium Liquid Argon Central Calorimeters
- Michigan State Univ., East Lansing, MI (United States)
The difference of the ratios of the high energy electron and pion responses ($$e/\pi$$) in the DO Uranium-liquid Argon central calorimeter is measured using the DO calorimeter trigger readout (shon integration time: 250 ns ) and precision readout (long integration time: 2.2$$\mu$$s). This measurement found a 5% difference in the e/$$\pi$$ ratio between short and long integration times, with estimated uncertainty of 2.3%.
