This document is the final report of ATLAS-CMS Dark Matter Forum, a forum organized by ATLAS and CMS collaborations with participation experts on theories Matter, to select minimal basis set dark matter simplified models that should support design early LHC Run-2 searches. A prioritized, compact benchmark proposed, accompanied studies parameter space these repository generator implementations. also addresses how apply Effective Field Theory formalism for collider searches present results...
The inert 2-Higgs Doublet Model (i2HDM) is a well-motivated minimal consistent Dark Matter (DM) model, but it rather challenging to test at the Large Hadron Collider (LHC) in parameter space allowed by relic density and DM direct detection constraints. This especially true when considering latest XENON 1T data on searches which we use here present best current combined limit i2HDM space. In this analysis, prospects advance exploitation of mono-jet signatures from LHC, emphasising that shape...
We analyze the potential of Fermilab Tevatron and CERN Large Hadron Collider (LHC) to study anomalous quartic vector--boson interactions (photon photon Z Z) W+ W-). Working in framework SU(2)_L X U(1)_Y chiral Lagrangians, we production photons pairs accompanied by (e+e-), (e nu), jet impose bounds on these new couplings, taking into account unitarity constraints. compare our findings with indirect limits coming from precision electroweak measurements as well presently available direct...
The exchange of gluons between heavy quarks produced in $e^+e^-$ interactions results an enhancement their production near threshold. We study QCD threshold effects $\gamma\gamma$ collisions. are relevant to quark by beamstrahlung and laser back-scattering future linear collider experiments. Detailed predictions for top, bottom charm presented.
We consider the transverse-momentum distribution of Higgs-boson production in gluon-gluon fusion. Using resummation techniques we obtain a result valid at all transverse momenta. The resulting distributions are compared with those from WW fusion mechanism and produced by event generators.
Detection at a hadron collider of the neutral Higgs bosons minimal supersymmetric extension standard model is not straightforward. Their decays to WW and ZZ pairs are either phase-space forbidden or suppressed absent coupling-constant level; thus, detection these in such modes will be possible. heavy-quark decay also almost certainly impossible due large QCD backgrounds. One possible mode (that proves useful for standard-model boson with mass below 2${m}_{W}$ 2${m}_{\mathrm{top}}$) via two...
We present a primer on the Standard Model of electroweak interaction. Emphasis is given to historical aspects theory's formulation. The radiative corrections are presented and its predictions for parameters compared with precise experimental data obtained at Z pole. Finally, we make some remarks perspectives discovery Higgs boson, most important challenge Model.
We study the pair production of neutral Higgs bosons through gluon fusion at hadron colliders in framework Minimal Supersymmetric Standard Model. present analytical expressions for relevant amplitudes, including both quark and squark loop contributions, allowing mixing between superpartners left- right-handed quarks. Squark contributions can increase cross section two CP-even by more than orders magnitude, if trilinear soft breaking parameter is large mass lighter eigenstate not too far...
We analyze the potential of CERN Large Hadron Collider to study anomalous quartic vector-boson interactions through production pairs accompanied by jets. In framework $\mathrm{SU}{(2)}_{L}\ensuremath{\bigotimes}\mathrm{U}{(1)}_{Y}$ chiral Lagrangians, we examine all effective operators order ${p}^{4}$ that lead new four-gauge-boson but do not alter trilinear vertices. our analyses, perform full tree-level calculation processes leading two jets plus pairs,...
We study the constraints on vertices $W^+W^- Z\gamma$, $W^+W^-\gamma\gamma$, and $ZZ\gamma\gamma$ that can be obtained from triple-gauge-boson production at next generation of linear $e^+e^-$ colliders operating in $\gamma\gamma$ mode. analyze processes $\gamma\gamma \to W^+W^-V$ ($V=Z$, or $\gamma$) show these reactions increase potential machines to search for anomalous four-gauge-boson interactions.
We study the potential effects of anomalous couplings third generation quarks to gauge bosons in rare $B$ decays. focus on constraints from flavor changing neutral current processes such as $\stackrel{\ensuremath{\rightarrow}}{b}s\ensuremath{\gamma}$ and $\stackrel{\ensuremath{\rightarrow}}{b}{\mathrm{sl}}^{+}{l}^{\ensuremath{-}}.$ consider both dimension-four dimension-five operators show that latter can give large deviations standard model still unobserved dilepton modes, even after bounds...
We perform a statistical combination of the ATLAS and CMS results for search heavy resonance decaying to pair vector bosons with $$ \sqrt{s}=8 TeV datasets collected at LHC. take into account six searches in hadronic semileptonic final states carried out by two collaborations. consider only public information provided HEPDATA database papers published refereed journals. interpret combined within context few benchmark new physics models, such as models predicting existence W′ or bulk...
Starting from general properties of a spin-2 field, we construct helicity wave functions in the framework Weyl-van der Waerden spinor formalism. We discuss here cases massless and massive particles.
We discuss mechanisms for the production of Higgs bosons minimal supersymmetric model at an ${e}^{+}$${e}^{\mathrm{\ensuremath{-}}}$ collider. In particular, we focus on those that are predicted to have zero or weak couplings vector-boson pairs, and hence cannot be produced by standard mechanisms.
We show that the accumulated CERN LEP-II data taken at $\sqrt{s}=130--206\mathrm{GeV}$ can establish more restrictive bounds on doubly charged bilepton couplings and masses than any other experiment so far. also analyze discovery potential of a prospective linear collider operating in both ${e}^{+}{e}^{\ensuremath{-}}$ $e\ensuremath{\gamma}$ modes.
Full detector simulation was among the largest CPU consumer in all CERN experiment software stacks for first two runs of Large Hadron Collider (LHC). In early 2010's, projections were that demands would scale linearly with luminosity increase, compensated only partially by an increase computing resources. The extension fast approaches to more use cases, covering a larger fraction budget, is part solution due intrinsic precision limitations. remainder corresponds speeding-up several factors,...
We analyze the production and detection of Higgs boson in next generation linear ${e}^{+}{e}^{\ensuremath{-}}$ colliders operating $e\ensuremath{\gamma}$ mode. In particular, we study mechanism $e+\ensuremath{\gamma}\ensuremath{\rightarrow}e\ensuremath{\gamma}\ensuremath{\gamma}\ensuremath{\rightarrow}e+H$, where one photon is generated via laser backscattering mechanism, while other radiated usual bremsstrahlung process. show that this most important for a 500 GeV collider...
We estimate the attainable limits on coefficients of dimension--6 operators from analysis Higgs boson phenomenology, in framework a $SU_L(2) \times U_Y(1)$ gauge-invariant effective Lagrangian. Our results, based data sample already collected by collaborations at Fermilab Tevatron, show that Higgs-vector couplings can be determined with unprecedented accuracy. Assuming all ``blind'' are same magnitude, we also able to impose more restrictive bounds anomalous vector-boson triple than present...
