Simple and statistically sound recommendations for analysing physical theories

(Cambridge U., DAMTP) ; Athron, Peter (Monash U. ; Nanjing Normal U.) ; Balázs, Csaba (Monash U.) ; Bagnaschi, Emanuele (PSI, Villigen) ; Bechtle, Philip (Bonn U.) ; Buchmueller, Oliver (Imperial Coll., London) ; Beniwal, Ankit (Louvain U., CP3) ; Bhom, Jihyun (Cracow, INP) et al.
Physical theories that depend on many parameters or are tested against data from many different experiments pose unique challenges to statistical inference. Many models in particle physics, astrophysics and cosmology fall into one or both of these categories. [...]

$\texttt{HEPfit}$: a Code for the Combination of Indirect and Direct Constraints on High Energy Physics Models
/ De Blas, J. (Padua U. ; INFN, Padua) ; Chowdhury, D. (Ecole Polytechnique, CPHT ; Orsay, LPT) ; Ciuchini, M. (INFN, Rome) ; Coutinho, A.M. (PSI, Villigen) ; Eberhardt, O.

$\texttt{HEPfit}$ is a flexible open-source tool which, given the Standard Model or any of its extensions, allows to $\textit{i)}$ fit the model parameters to a given set of experimental observables; $\textit{ii)}$ obtain predictions for observables. $\texttt{HEPfit}$ can be used either in Monte Carlo mode, to perform a Bayesian Markov Chain Monte Carlo analysis of a given model, or as a library, to obtain predictions of observables for a given point in the parameter space of the model, allowing $\texttt{HEPfit}$ to be used in any statistical framework.

Report from Working Group 2 : Higgs Physics at the HL-LHC and HE-LHC

(Milan Bicocca U.) ; Alves, A. (U. Sao Paulo (main)) et al.
The discovery of the Higgs boson in 2012, by the ATLAS and CMS experiments, was a success achieved with only a percent of the entire dataset foreseen for the LHC. It opened a landscape of possibilities in the study of Higgs boson properties, Electroweak Symmetry breaking and the Standard Model in general, as well as new avenues in probing new physics beyond the Standard Model.

Impact of a Higgs boson at a mass of 126 GeV on the standard model with three and four fermion generations
/ Eberhardt, Otto (KIT, Karlsruhe, TTP) ; Herbert, Geoffrey (Humboldt U., Berlin) ; Lacker, Heiko (Humboldt U., Berlin) ; Lenz, Alexander (CERN ; Durham U.) ; Menzel, Andreas (Humboldt U., Berlin) ; Nierste, Ulrich (KIT, Karlsruhe, TTP) ; Wiebusch, Martin (KIT, Karlsruhe, TTP)
We perform a comprehensive statistical analysis of the standard model (SM) with three and four generations using the latest Higgs search results from LHC and Tevatron, the electroweak precision observables (EWPOs) measured at LEP and SLD and the latest determinations of M_W, m_t and alpha_s. For the three-generation case we analyse the tensions in the electroweak fit by removing individual observables from the fit and comparing their predicted values with the measured ones. [...]

Status of the fourth fermion generation before ICHEP2012: Higgs data and electroweak precision observables
/ Eberhardt, Otto (KIT, Karlsruhe, TTP) ; Lenz, Alexander (CERN) ; Menzel, Andreas (Humboldt U., Berlin) ; Nierste, Ulrich (KIT, Karlsruhe, TTP) ; Wiebusch, Martin (KIT, Karlsruhe, TTP)
We perform a global fit of the parameters of the Standard Model with a sequential fourth generation (SM4) to LHC and Tevatron Higgs data and electroweak precision data. We find that the minimal chi-square value of the SM4 is larger than that of the Standard Model with three generations (SM3) by 8 units. [...]

Joint analysis of Higgs decays and electroweak precision observables in the Standard Model with a sequential fourth generation
/ Eberhardt, Otto (KIT, Karlsruhe, TTP) ; Herbert, Geoffrey (Humboldt U., Berlin) ; Lacker, Heiko (Humboldt U., Berlin) ; Lenz, Alexander (CERN) ; Menzel, Andreas (Humboldt U., Berlin) ; Nierste, Ulrich (KIT, Karlsruhe, TTP) ; Wiebusch, Martin (KIT, Karlsruhe, TTP)
We analyse the impact of LHC and Tevatron Higgs data on the viability of the Standard Model with a sequential fourth generation (SM4), assuming Dirac neutrinos and a Higgs mass of 125 GeV. To this end we perform a combined fit to the signal cross sections of pp -> H -> gamma gamma,ZZ*,WW* at the LHC, to p pbar -> VH -> V b bbar (V = W, Z) at the Tevatron and to the electroweak precision observables.
