80. The Z transverse momentum distribution (Tevatron)

38. Precision Top Quark Mass From a Simultaneous Fit in l+j and l+l Channels Using 2fb^-1

M. Wojciech Fedorko (University of Chicago)

04/03/2008 17:07

We present a measurement of the top quark mass employing the template method with data samlpe collected by the CDF Run II detector corresponding to integrated luminosity of 2fb^-1. Lepton+Jets and Dilepton final states are selected. For each event in the Lepton+Jets channel we apply kinematic constraints on the pair of top quarks and their decay products to determine a reconstructed top quark...

41. BiPo prototype measurements for SuperNEMO

M. Mathieu Bongrand (LAL - Universite Paris-Sud 11)

The SuperNEMO project requires high radiopurity levels of the 2beta source foils: 10 uBq/kg in 214Bi and 2 uBq/kg in 208Tl. Today, best detectors can't reach these levels for big masses in a reasonable time. That's why the collaboration decided to build a dedicated detector for these measurements. Looking for BiPo processes (beta decay + delayed alpha decay) the BiPo detector has to measure...

35. Search for the Higgs boson in the ZH->nunubb channel at D0

M. Christophe Ochando (LAL)

04/03/2008 17:21

A search for the standard model Higgs boson has been performed in 2.1 fb-1 of p_pbar collisions at 1.96 TeV, collected with the D0 detector at the Fermilab TeVatron. The final state considered is a pair of acoplanar b jets, as expected from the reaction p_pbar->HZ->bbnunu. The search is also sensitive to the HW->bblnu, when the charged lepton is not identified. Boosted decision trees were...

82. SM Higgs search in WH->lvbb : 2 fb-1 (Tevatron)

83. Higgs production through weak boson fusion in Atlas

53. Yukawa corrections to b anti-b H production (LHC)

M. Duc Ninh Le (LAPTH)

04/03/2008 17:42

We investigate the leading one-loop Yukawa corrections to the process $pp->b\overline{b}H$ in the SM. We find that the NLO correction to the cross section is about $-4\mathrm{\%}$ if the Higgs mass is $120$GeV. In the limit of vanishing bottom-Higgs Yukawa coupling the cross section is generated solely at the loop level. This contribution is very small at $M_H\sim 120$GeV and increases with growing...

84. MSSM with heavy scalars: Discovery potential at LHC

32. Search of $K_S\to e^{+}{e}^{-}$ decay with KLOE

M. Flavio Archilli (University "Tor Vergata" (Rome))

04/03/2008 17:56

The KLOE detector is operated at DA$\mathrm{\Phi }$NE, an $e^{+}{e}^{-}$ collider running at a center of mass energy $W=m_{\varphi }\sim 1019.45$~MeV. $\varphi$ mesons decay 34\% of the time to a $K_S{K}_L$ pair. Detection of a $K_L$ thus signals the presence of, ``tags'', a $K_S$ and vice versa. With this technique, we select a pure $K_S$ beam, which permits studies of suppressed $K_S$ decays...
