Abstract

We present a measurement of the polarization-temperature angular cross power spectra, {\ltTE\gt and \ltTB\gt, of the cosmic microwave background. The result is based on \~{}200 hr of data from eight polarization-sensitive bolometers operating at 145 GHz during the 2003 flight of BOOMERANG. We detect a significant \ltTE\gt correlation in the l-range between 50 and 950 with a statistical significance of \gt3.5 $\sigma$. Contamination by polarized foreground emission and systematic effects are negligible in comparison with statistical uncertainties. The spectrum is consistent with previous detections and with the ``concordance model'' that assumes adiabatic initial conditions. This is the first measurement of polarization-temperature angular cross-power spectra using bolometric detectors. }
