This Report summarizes the results of activities in 2012 and first half 2013 LHC Higgs Cross Section Working Group. The main goal working group was to present state art Physics at LHC, integrating all new that have appeared last few years. report follows Handbook Sections: 1. Inclusive Observables (CERN-2011-002) second 2. Differential Distributions (CERN-2012-002). After discovery a boson mid-2012 this focuses on refined prediction Standard Model (SM) phenomenology around experimentally...
Results are presented for the purity of three commercial brands Ca chelator EGTA [ethyleneglycol-bis(beta-aminoethylether)-N,N'-tetraacetic acid] as determined with pH-metric and oxalate precipitation methods other techniques. The effect that observed degree hydration (2-4%) has on calculated values [Ca2+] in Ca-EGTA solutions is described reference to a theoretical dose-response relationship. In addition corrections purity, adjustments necessary allow ionic strength correction pH readings...
We perform an up-to-date global fit of top quark effective theory to experimental data from the Tevatron, and LHC Runs I II. Experimental includes total cross-sections up 13 TeV, as well differential distributions, for both single pair production. also include width, charge asymmetries, polarisation information decay products. present bounds on coefficients dimension six operators, examine interplay between inclusive measurements, Tevatron / data. All results are currently in good agreement...
In this paper we present a global fit of beyond the Standard Model (BSM) dimension-six operators relevant to top quark sector all currently available production cross-section measurements, namely parton-level top-pair and single at LHC Tevatron. Higher order QCD corrections are modeled using differential $K$-factors, use novel fast-fitting techniques developed in context Monte Carlo event generator tuning perform fit. This allows us provide new, fully correlated model-independent bounds on...
We propose and study a constrained version of the exceptional supersymmetric standard model (${\mathrm{E}}_{6}\mathrm{SSM}$), which we call ${\mathrm{cE}}_{6}\mathrm{SSM}$, based on universal high energy scalar mass ${m}_{0}$, trilinear coupling ${A}_{0}$ gaugino ${M}_{1/2}$. derive renormalization group (RG) Equations for including extra $U(1{)}_{N}$ gauge factor low-energy matter content involving three 27 representations ${\mathrm{E}}_{6}$. perform numerical RG analysis imposing usual...
A bstract We study an effective theory of flavour in which the SU(2) L interaction is ‘flavour-deconstructed’ near TeV scale. This arises, for example, UV models that unify all three generations left-handed fermions via Sp(6) symmetry. Flavour-universality electroweak force emerges accidentally (but naturally) from breaking $$ {\prod}_{i=1}^3\textrm{SU}{(2)}_{L,i} <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:msubsup> <mml:mo>∏</mml:mo> <mml:mrow> <mml:mi>i</mml:mi>...
Large area nickel antidot arrays with density up to 10^10 /cm^2 have been fabricated by depositing onto anodic aluminum oxide membranes that contain lattices of nanopores. Electron microscopy images show a high degree order the arrays. Various sizes and shapes antidots were observed increasing thickness deposited nickel. New features appear in both magnetization transport measurements when external magnetic field is parallel current direction, including an enhancement nonmonotonous...
Cross sections for K-p charge exchange, based on new data equal in statistics to the sum of those all previous determinations below 300 MeV/c, are presented. The results confirm an earlier observation by this collaboration that measurements these cross at low momentum were significantly underestimated. Evidence presence P wave scattering is
We discuss the predictions of a constrained version exceptional supersymmetric standard model (cE6SSM), based on universal high energy soft scalar mass m_0, trilinear coupling A_0 and gaugino M_1/2. predict supersymmetry (SUSY) spectrum containing light gluino, wino-like neutralino chargino pair bino-like neutralino, with other sparticle masses except lighter stop being much heavier. In addition, cE6SSM allows possibility exotic colour triplet charge 1/3 fermions scalars, leading to early...
1. The tension levels of the contractures induced in frog atrial trabeculae by reduction bathing Na concentration have been investigated over a wide range [Na+]o and [Ca2+]o, making use EGTA to buffer [Ca2+]o under 10(-5)M. 2. relationship between quotient [Ca2+]o/[Na+]2o is only an apparent one, holds approximately for concentrations as low 1-5 mM. 3. However, depends on absolute values both [Na+]o. 4. Extracellular Ca essential factor production. results indicate threshold near 5 X 10(-8)...
1. The force of contraction and the membrane potentials have been measured from preparations frog heart, with methods that also allow rapid exchange extracellular fluid. 2. In regularly beating preparations, caffeine induces only weak contractures at temperatures above 15° C, but it does cause a marked potentiation twitch responses; longer exposure results in depression contraction. build up decline strength, on addition removal approximates to single exponential, time constant 26–45 sec,...
We study the parameter space of constrained exceptional supersymmetric standard model (cE6SSM) consistent with a Higgs signal near 125 GeV and LHC searches for squarks, gluinos Z'. The cE6SSM correct electroweak symmetry breaking, is represented by scans in (m0, M1/2) plane fixed Z' mass tan beta, squark, gluino masses plotted as contours this plane. find that only arises sufficiently large mass, mostly above current limits, particular regions squark corresponding to multi-TeV masses, but...
