Low Mass Standard Model Higgs Limit at the Tevatron

PDF Version Also Available for Download.

Description

The searches for the Standard Model (SM) Higgs Boson at the Fermilab Tevatron by the CDF and D0 experiments are presented. Their state of the art techniques, including maximizing Higgs signal acceptance, reducing background through b-jet ID, and with Multi-Variate discrimination between signal and background, are elucidated. The two experiments are able to achieve a sensitivity of three to five times SM cross section ({sigma}{sub SM}) at the benchmark mass point of m{sub H} = 115 GeV/c{sup 2} using the main search channels WH {yields} lvbb, ZH {yields} vvbb, and ZH {yields} llbb, and on combining all the channels from ... continued below

The two experiments are able to achieve a sensitivity of three to five times SM cross section ({sigma}{sub SM}) at the benchmark mass point of m{sub H} = 115 GeV/c{sup 2} using the main search channels WH {yields} lvbb, ZH {yields} vvbb, and ZH {yields} llbb, and on combining all the channels from CDF and D0, the observed (expected) limit is 1.56 (1.45) x {sigma}{sub SM}. The present expected limit is 1.8 x {sigma}{sub SM} or below for the entire low mass range, and sensitivity projections at present anticipate in Tevatron Run II a 3{sigma} sensitivity achievement for m{sub H} = 115 GeV/c{sup 2}.
