After about four years of operation\, the accelerator will be upgrad ed to the so-called Phase 1: a peak luminosity of 2x10^34 cm^(-2)s^(-1) is expected\, resulting in an increase by a factor of two with respect to th e initial specifications. In this occasion\, the CMS pixel detector will b e replaced with an upgraded system\, with major changes to the mechanical structure\, front-end electronics and the cooling system. In this presenta tion I discuss the performance of the pixel detector and track reconstruct ion with the new layout\, based on Monte Carlo simulations.\n\nhttp://indi co.cern.ch/contributionDisplay.py?contribId=20&sessionId=14&confId=80223 LOCATION: URL:http://indico.cern.ch/contributionDisplay.py?contribId=20&sessionId=14 &confId=80223 END:VEVENT BEGIN:VEVENT SUMMARY:to be defined DTSTART;VALUE=DATE-TIME:20100124T094000Z DTEND;VALUE=DATE-TIME:20100124T100000Z DTSTAMP;VALUE=DATE-TIME:20130523T162039Z UID:indico-contribution-80223-21@cern.ch DESCRIPTION:Speakers: \nhttp://indico.cern.ch/contributionDisplay.py?contr ibId=21&sessionId=14&confId=80223 LOCATION: URL:http://indico.cern.ch/contributionDisplay.py?contribId=21&sessionId=14 &confId=80223 END:VEVENT BEGIN:VEVENT SUMMARY:The influence of WIMP dark matter on low-mass stars DTSTART;VALUE=DATE-TIME:20100120T142000Z DTEND;VALUE=DATE-TIME:20100120T144000Z DTSTAMP;VALUE=DATE-TIME:20130523T162039Z UID:indico-contribution-80223-1@cern.ch DESCRIPTION:Speakers: CASANELLAS\, Jordi ()\nThe formation and evolution o f low-mass stars within dense halos of dark matter (DM) leads to evolution scenarios quite different from the classical stellar evolution. For high DM densities\, these stars stop their gravitational collapse before reachi ng the main sequence. Such stars remain indefinitely in an equilibrium sta te with lower effective temperatures\, the annihilation of captured DM par ticles in their core being the only source of energy. In the case of lower DM densities\, these proto-stars continue their collapse and progress thr ough the main sequence burning hydrogen at a lower rate. I will also show the strong dependence of the effective temperature and luminosity of these stars on the characteristics of the DM particles (mass\, scattering cross sections) and how this can be used as an alternative method for DM resear ch.\n\nhttp://indico.cern.ch/contributionDisplay.py?contribId=1&sessionId= 14&confId=80223 LOCATION: URL:http://indico.cern.ch/contributionDisplay.py?contribId=1&sessionId=14& confId=80223 END:VEVENT BEGIN:VEVENT SUMMARY:Model-independent cosmological constraints from the CMB DTSTART;VALUE=DATE-TIME:20100120T140000Z DTEND;VALUE=DATE-TIME:20100120T142000Z DTSTAMP;VALUE=DATE-TIME:20130523T162039Z UID:indico-contribution-80223-0@cern.ch DESCRIPTION:Speakers: VONLANTHEN\, Marc ()\nWe analyse CMB data in a manne r which is as model-independent as possible. We encode the effects of late -time cosmology into a single parameter which describes the distance to th e last scattering surface\, similar to the shift parameter\, and exlude lo w multipoles\, up to l 40 from the analysis. We consider the WMAP five-y ear as well as ACBAR 2008 observations. We obtain constraints on !b\, !m a nd ns\, which can be applied as priors in other analysis without committin g to a specific model of the late universe.\nSynopsis of the talk\nThe cos mic microwave background (CMB) is one of the most important cosmological p robes. The pattern of acoustic oscillations of the baryon-photon plasma is imprinted on the CMB at the time of decoupling\, and then rescaled (and o n large scales modified) as the CMB photons propagate from the last scatte ring surface to the observer. The CMB is thus sensitive to cosmological pa rameters in two ways\, via the physics at decoupling and via evolution in the later universe. While the physics at decoupling (essentially atomic ph ysics and general relativity in the linear regime) is well understood\, th e evolution at late times deviates from the predictions of the linearly pe rturbed FRW models with radiation and matter. The difference may be due to an exotic matter component with negative pressure\, deviation of gravity from general relativity or a breakdown of the homogeneous and isotropic ap proximation. It is not known which of these possibilities is correct\, and there are large differences between the various models. It is therefore w orthwhile to analyse the CMB in a manner which is as independent of the de tails of late-time cosmology as possible. On the one hand\, this makes it clear what constraints all models of late-time cosmology\, whatever their details\, have to satisfy in order to agree with the CMB observations. On the other hand\, such analysis gives limits on the physical parameters at decoupling that are independent of the details of late-time cosmology.This is particularly important for cosmological parameters such as the density of baryons or dark matter which are used as constraints on particle physi cs models involving e.g. supersymmetry or baryogenesis\, which have otherw ise nothing to do with latetime cosmology. Such a separation of constraint s is possible because the physics after decoupling affects the CMB in a ra ther limited manner\, by changing the angular scale of the CMB pattern (ap art from the low multipoles). We analyse the CMB by encoding this effect i n a single parameter\, the angular diameter distance to the last scatterin g surface. We also aim to be transparent about how the different cosmologi cal parameters enter the analysis\, and which assumptions are made. Theref ore\, I will begin with a short discussion about how the early and late ph ysics affects the CMB and explain our assumptions. I will then present the results of the analysis of the WMAP 5-year and ACBAR 2008 data and give c onstraints on cosmological parameters\, and finally\, I will discuss the r esults and conclude.\n\nhttp://indico.cern.ch/contributionDisplay.py?contr ibId=0&sessionId=14&confId=80223 LOCATION: URL:http://indico.cern.ch/contributionDisplay.py?contribId=0&sessionId=14& confId=80223 END:VEVENT BEGIN:VEVENT SUMMARY:$B_s0$ branching fractions measurements at Belle DTSTART;VALUE=DATE-TIME:20100120T153000Z DTEND;VALUE=DATE-TIME:20100120T155000Z DTSTAMP;VALUE=DATE-TIME:20130523T162039Z UID:indico-contribution-80223-3@cern.ch DESCRIPTION:Speakers: LOUVOT\, Remi ()\nThe general-purpose Belle dectecto r is located at the KEK $B$ factory (Tsukuba\, Japan). This asymmetric $e^ +e^-$ collider was designed to produce a large number of $B0$ and $B^+$ me son pairs by running at a center-of-mass energy near the $\\Upsilon(4S)$ r esonance ($\\sqrt s\\approx10.58$ GeV). By increasing the energy above the $B_s0\\bar B_s0$ threshold\, the large potential of the $B$ factories for exploring the poorly-known $B_s0$ meson was quickly demonstrated. So far\ , the Belle detector have accumulated more than $\\approx100$ fb$^{-1}$ at the $\\Upsilon(5S)$ energy ($\\sqrt s\\approx10.87$ GeV) representing $\\ sim3$ millions of $B_s0$ pairs. This represents 99\\% of the world's sampl e at this energy. The study of the $B_s0$ is of high interest and the Bell e sample\, where the number of produced $B_s0$ is accessible\, is a unique chance to measure precisely an absolute branching fraction. The measureme nt of five $B_s0$ branching fractions using the first 23.6 fb$^{-1}$ of da ta will be described\, and prospects for improving the precision through a better normalization will be discussed. The full reconstruction of a clea n $B_s0\\to D_s^-\\pi^+$ sample ($161\\pm15$ events) provided the current most precise measured $B_s0$ branching fraction. Additionally\, the $B_s^{ \\ast}$ and $B_s0$ masses and the $B_s0$ production-mode fractions were al so measured. A $3.5\\sigma$ evidence for its Cabibbo-suppress counterpart $B_s0\\to D_s^{\\mp}K^{\\pm}$ was obtained. This analysis was recently ext ended to three other dominant modes including photons in their final state s and led to the first observations of the $B_s0\\to D_s^{\\ast-}\\pi^+$\, $B_s0\\to D_s^-\\rho^+$ and $B_s0\\to D_s^{\\ast-}\\rho^+$ modes.\n\nhttp ://indico.cern.ch/contributionDisplay.py?contribId=3&sessionId=14&confId=8 0223 LOCATION: URL:http://indico.cern.ch/contributionDisplay.py?contribId=3&sessionId=14& confId=80223 END:VEVENT BEGIN:VEVENT SUMMARY:Primordial magnetic fields and their gravitational wave production DTSTART;VALUE=DATE-TIME:20100120T144000Z DTEND;VALUE=DATE-TIME:20100120T150000Z DTSTAMP;VALUE=DATE-TIME:20130523T162039Z UID:indico-contribution-80223-2@cern.ch DESCRIPTION:Speakers: FENU\, Elisa ()\nI will briefly review the current s tatus of magnetic field observations in galaxies and\nclusters.

For this purpo se the development of additional sub-detectors is needed. One option would be the use of fast scintillation detectors as muon taggers for a L1 trigg er support.
