74. Higgs Physics in Warped Extra Dimensions

M. Florian Goertz (Johannes Gutenberg-Universität Mainz)

17/03/2011 19:20

Theory

YSF (Young Scientists Forum)

Warped Extra Dimensions provide an elegant solution to both the gauge hierarchy problem and the flavor puzzle of the Standard Model of Particle Physics. The hierarchies between the electroweak and the Planck scale as well as those within the flavor sector are addressed in a five-dimensional setup with non-factorizable geometry. As the Higgs boson has to reside close to the TeV boundary, it...

91. Estimation of SM backgrounds to SUSY search in the 1-lepton+jets+ETMiss channel

Mme Jeanette Lorenz (Fakultaet fuer Physik, LMU Muenchen)

17/03/2011 19:28

Experiment

YSF (Young Scientists Forum)

First results of the SUSY search in the 1-lepton+jets+ETMiss channel with the ATLAS experiment were made public recently. A precise understanding of the Standard Model backgrounds was crucial for these results. This talk will give a short overview about the Standard Model background estimation techniques and results.

63. Yukawa unification in SUSY SO(10)

M. Marcin Badziak (University of Warsaw)

17/03/2011 19:36

Theory

YSF (Young Scientists Forum)

In simple SO(10) SUSY GUT the top, bottom and tau Yukawa couplings unify at the GUT scale. It is well known that Yukawa unification (YU) consistent with radiative electroweak symmetry breaking requires non-universal scalar masses at the GUT scale. YU prefers also the negative sign of parameter \mu. However, negative \mu is typically disfavoured by the measurements of the muon anomalous...

117. Jet Production cross section measurement with ATLAS

50. Search for rare Standard Model processes in the MET+b-jets signature at CDF

M. Karolos Potamianos (Purdue University)

17/03/2011 19:52

Experiment

YSF (Young Scientists Forum)

We present state of the art techniques to effectively reject instrumental backgrounds from searches in the MET+b-jets signature.

105. Top-quark pair cross-section measurement in the lepton+jets channel

M. Michele Pinamonti (INFN Udine & University of Trieste)

17/03/2011 20:00

Experiment

YSF (Young Scientists Forum)

A measurement of the production cross-section for top quark pairs in pp collisions at sqrt{s} = 7 TeV is presented using data recorded with the ATLAS detector. Events are selected in the lepton+jets topology by requiring a single lepton (electron or muon), large missing transverse energy and at least three jets. No explicit identification of secondary vertices inside jets (b-tagging) is...

69. SUSY flavour problem in 5D GUTs

M. sylvain fichet (LPSC)

17/03/2011 20:08

Theory

YSF (Young Scientists Forum)

In 5D SUSY GUTs, wave-function localization permits to reproduce flavour hierarchy. As this mechanism also acts on SUSY breaking parameters, it can potentially solve the SUSY flavour problem. Here we carry out a quantitative analysis of the case of Holographic Grand Unification, which is a warped SU(6) GUT with pNGB Higgses on the IR brane. To break SUSY, we use independently radion...

90. Charmless two-dody B hadron decays at LHCb with 2010 data

M. Stefano Perazzini (Università & INFN Bologna)

17/03/2011 20:16

Experiment

YSF (Young Scientists Forum)

The LHCb experiment is designed to perform flavour physics measurements at the Large Hadron Collider. Using data collected during the 2010 run, we reconstructed a sample of Hb --> h+h'- decays, where Hb can be either a B0 meson, a Bs0 meson or a Lambda_b baryon, while h and h′ stand for pi, K or p. Such decays are sensitive probes of the Cabibbo-Kobayashi-Maskawa matrix and have the potential...
