@article{10902/2081, year = {2009}, month = {7}, url = {http://hdl.handle.net/10902/2081}, abstract = {We present new limits on resonant tb̅ production in pp̅ collisions at √s=1.96  TeV, using 1.9  fb-1 of data recorded with the CDF II detector at the Fermilab Tevatron. We reconstruct a candidate tb̅ mass in events with a lepton, neutrino candidate, and two or three jets, and search for anomalous tb̅ production as modeled by W′→tb̅ . We set a new limit on a right-handed W′ with standard model-like coupling, excluding any mass below 800  GeV/c2 at 95% C.L. The cross section for any narrow, resonant tb̅ production between 750 and 950  GeV/c2 is found to be less than 0.28 pb at 95% C.L. We also present an exclusion of the W′ coupling strength versus W′ mass over the range 300–950  GeV/c2.}, publisher = {American Physical Society}, publisher = {Physical Review Letters, vol. 103 iss. 4, art. num. 041801 (2009)}, title = {Search for the Production of Narrow tb̅ Resonances in 1.9  fb-1 of pp̅ Collisions at √s=1.96  TeV}, author = {Aaltonen, Timo Antero and Akimoto, Takashi and Álvarez González, Bárbara and Amerio, Silvia and Amidei, Dante and Anastassov, Anton and Annovi, Alberto and Antos, Jaroslav and Apollinari, Giorgio and Apresyan, Artur and Casal Laraña, Bruno and Cuevas Maestro, Francisco Javier and Gómez Gramuglio, Gervasio and Rodrigo Anoro, Teresa and Ruiz Jimeno, Alberto and Scodellaro, Luca and Vila Álvarez, Iván and Vilar Cortabitarte, Rocío and Arisawa, Tetsuo and Adelman, Jahred}, }
