Inherent Biases in the Ansatz Function Method used to Search for New Particles Decaying to Two-Jets in pbarp Collisions
Abstract
Searches for new resonant phenomena on top of a continuum spectra need to make assumptions regarding the shape of the continuum spectra. The Ansatz function method used in previous searches for new particles decaying to dijets is investigated and found to have inherent biases that cause the 95% confidence limits on the signal cross-section to be miss-measured by up to 30 to 50%.
