Top quark production offers the unique opportunity to search for a charged Higgs;boson (H+/-), as the contribution from t-->H+ b-->tau(+) nu b can be large in extensions of the standard model. We use results from a search for top quark pair production by the Collider Detector at Fermilab (CDF) in the e tau + E-T + jets and mu tau + E-T + jets signatures to set an upper limit on the branching ratio of B(t-->H+ b) in 106 pb(-1) of data. The upper limit is in the range 0.5 to 0.6 at 95% C.L. for H+ masses in the range 60 to 160 GeV, assuming the branching ratio for H+-->tau nu is 100%. The tau lepton is detected through its 1-prong and 3-prong hadronic decays.

Abstract
Top quark production offers the unique opportunity to search for a charged Higgs;boson (H+/-), as the contribution from t-->H+ b-->tau(+) nu b can be large in extensions of the standard model. We use results from a search for top quark pair production by the Collider Detector at Fermilab (CDF) in the e tau + E-T + jets and mu tau + E-T + jets signatures to set an upper limit on the branching ratio of B(t-->H+ b) in 106 pb(-1) of data. The upper limit is in the range 0.5 to 0.6 at 95% C.L. for H+ masses in the range 60 to 160 GeV, assuming the branching ratio for H+-->tau nu is 100%. The tau lepton is detected through its 1-prong and 3-prong hadronic decays.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
