  1. 117. Post-Inflation H relaxation and matter-antimatter asymmetry
    Alexander Kusenko (UCLA)
    17/03/2015 08:30
    Theory
    Ordinary
  2. 9. Higgs and searches for new phenomena at the Tevatron
    Dr Costas Vellidis (Fermilab)
    17/03/2015 08:50
    Experiment
    Ordinary
    The Tevatron experiments complete their programs of searches for new physics using their full data samples. The most recent results come from CDF, with searches in the Higgs, heavy boson, magnetic monopole, and dark matter sectors. Constraints on models of the Higgs boson with alternative spin-parity quantum numbers than the SM prediction; a search for fermiophobic Higgs boson...

  3. 91. ATLAS Run1 final results, prospectives for Run2
    Giacinto Piacquadio (SLAC)
    17/03/2015 09:10
    Experiment
    Ordinary
    Presentation of the main final ATLAS Run-I results on the Higgs boson on- and off-shell couplings, on the mass, spin/CP measurements and search for Higgs boson to invisible decays. This talk will concentrate on describing all the main results in the single channels, leaving the combination of channels to a dedicated talk later in the same session. Not covered: (1) searches for exotic/rare...

  4. 112. CMS Run1 final results, prospectives for Run2 (and HL-LHC)
    M. Josh Bendavid (CERN)
    17/03/2015 09:30
    Experiment
    Ordinary
    Presentation of final CMS Run 1 results for scalar signal strengths, mass, width and spin/CP. Focus will be on single-channel results in the main Standard Model channels. Prospects for Run 2 and HL-LHC will also be briefly discussed.

  8. 51. Aligned two doublet model
    Alejandro Celis (Ludwig Maximilian University of Munich)
    17/03/2015 17:00
    Theory
    Ordinary
    I will discuss the phenomenology of models with two scalar doublets and no flavour-changing neutral currents at tree-level. Implications of flavour constraints and measurements of the 125 GeV scalar properties will be discussed keeping the generic Yukawa structure of the aligned two doublet model. Particular limits with a reduced number of free parameters, such as the usual models based on...

  9. 63. Search for rare and exotic Higgs decays and production at the LHC: status and perspectives
    Dr Paolo Meridiani (INFN)
    17/03/2015 17:20
    Experiment
    Ordinary
    I will review the status of the searches for BSM physics in the Higgs sector at the LHC performed by the ATLAS and CMS experiment. In particular, I will concentrate on rare and exotic Higgs decay and production modes. I will conclude giving perspectives for the Run 2 and beyond

  10. 77. CMS High mass WW and ZZ Higgs search with the complete LHC Run1 statistics
    Dr Mario Pelliccioni (Istituto Nazionale di Fisica Nucleare)
    17/03/2015 17:40
    Experiment
    Ordinary
    A search for an additional Higgs boson in the $H \rightarrow WW$ and $H \rightarrow ZZ$ decay channels is reported. For Higgs boson masses in the range 145 < $m_H$ < 1000 GeV, limits from the search for a heavy resonance in the context of an electroweak singlet extension of the standard model are presented. Additionally, the combined upper limit at the 95% confidence level on the product of...

  11. 26. EW vacuum stability depends upon Planck scale physics
    Prof. Vincenzo Branchina (University of Catania)
    17/03/2015 18:00
    Theory
    Ordinary
    According to the usual analysis, the presence of new physics at very high energy scales (Planck scale) has no impact on the stability condition of the EW vacuum, and the latter depends only on the values of the Higgs and top masses (M_H and M_t). However, it has been recently demonstrated that new physics interactions, even if they show up only at very high energies, can strongly...

    Dr Alberto Salvio (Universidad Autonoma de Madrid)
    17/03/2015 18:45
    Theory

  13. 109. The LHC machine: Run 2 and beyond
    Mike Lamont (CERN)
    17/03/2015 19:05
    Experiment
    Ordinary
    The LHC is exiting a two-year long shutdown (LS1) and the start of Run 2 is imminent. The key consolidation measures of LS1 are briefly recalled and the prospects for 2015 and Run 2 are outlined. The high luminosity LHC project (HL-LHC) is now well established. The key projects goals are enumerated and specific measures planned to meet the challenging luminosity targets are introduced. The...
