The physics programme and the design are described of a new collider for particle nuclear physics, Large Hadron Electron Collider (LHeC), in which newly built electron beam 60 GeV, up to possibly 140 energy collides with intense hadron beams LHC. Compared HERA, kinematic range covered is extended by factor twenty negative four-momentum squared, $Q^2$, inverse Bjorken $x$, while luminosity $10^{33}$ cm$^{-2}$s$^{-1}$ LHeC projected exceed integrated HERA two orders magnitude. devoted an...
We present the report of hadronic working group BOOST2010 workshop held at University Oxford in June 2010. The first part contains a review potential decays highly boosted particles as an aid for discovery LHC and discussion status tools developed to meet challenge reconstructing isolating these topologies. In second part, we new results comparing performance jet grooming techniques top tagging algorithms on common set benchmark channels. also study sensitivity substructure observables...
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...
This document a outlines set of simplified models for dark matter and its interactions with Standard Model particles. It is intended to summarize the main characteristics that these have when applied searches at LHC, provide number useful expressions reference. The list includes both s-channel t-channel scenarios. For s-channel, spin-0 spin-1 mediations are discussed, also realizations where Higgs particle provides portal between visible sectors. guiding principles underpinning proposed...
The inert two-Higgs-doublet model (i2HDM) is a theoretically well-motivated example of minimal consistent dark matter (DM) which provides monojet, mono-$Z$, mono-Higgs, and vector-boson-$\mathrm{fusion}+{\mathbit{E}}_{\mathrm{T}}^{\mathrm{miss}}$ signatures at the LHC, complemented by signals in direct indirect DM search experiments. In this paper we have performed detailed analysis constraints full five-dimensional parameter space i2HDM, coming from perturbativity, unitarity, electroweak...
We study production of Kaluza-Klein (KK) gluons at the Large Hadron Collider (LHC) in framework a warped extra dimension with standard model fields propagating bulk. show that detection KK gluon is challenging since its suppressed by small couplings to proton's constituents. Moreover, decays mostly top pairs due an enhanced coupling and hence broad. Nevertheless, we demonstrate for ${M}_{\mathrm{KKG}}\ensuremath{\lesssim}4\text{ }\text{ }\mathrm{TeV}$, $100\text{...
We present the Large Hadron Collider (LHC) discovery potential in ${Z}^{\ensuremath{'}}$ and heavy neutrino sectors of a $U(1{)}_{B\ensuremath{-}L}$ enlarged standard model also encompassing 3 Majorana neutrinos. This exhibits novel signatures at LHC, most interesting arising from decay chain involving neutrinos, eventually decaying into leptons jets. In particular, this signature allows one to measure masses involved. addition, over large region parameter space, neutrinos are rather...
We present phase space distributions and multiplicities of K+, K−, ϕ mesons produced in Ar+KCl reactions at a kinetic beam energy 1.756 GeV/nucleon measured with the HADES spectrometer. The inverse slope parameters yields kaons supplement systematics previous measurements. percentage K− coming from decay is found to be 18±7%.6 MoreReceived 9 March 2009DOI:https://doi.org/10.1103/PhysRevC.80.025209©2009 American Physical Society
We present transverse momentum spectra, rapidity distribution and multiplicity of $ \Lambda$ -hyperons measured with the HADES spectrometer in reaction Ar(1.76AGeV) + KCl . The yield \Xi^{{-}}_{}$ is calculated from our previously reported /( \Sigma^{{0}}_{}$ ) ratio compared to other strange particle multiplicities. Employing a strangeness balance equation multiplicities yet unmeasured \Sigma^{{\pm}}_{}$ can be estimated. Finally statistical hadronization model used fit yields \pi^{-}_{}$ ,...
We discuss the prospects for setting limits on or discovering spin-1 $Z'$ bosons using early LHC data at 7 TeV. Our results are based narrow width approximation in which leptonic Drell-Yan boson production cross-section only depends mass together with two parameters $c_u$ and $c_d$. carefully experimental cuts that should be applied tabulate theoretical next-to-next-to-leading order corrections must included. Using these approach then provides a safe, convenient unbiased way of comparing...
We present a search for the e+e− decay of hypothetical dark photon, also named U vector boson, in inclusive dielectron spectra measured by HADES p(3.5 GeV) + p, Nb reactions, as well Ar (1.756 GeV/u) KCl reaction. An upper limit on kinetic mixing parameter squared ϵ2 at 90% CL has been obtained mass range MU=0.02–0.55 GeV/c2 and is compared with world data set. For masses 0.03–0.1 GeV/c2, lowered respect to previous results, allowing now exclude large part region favored muon g−2 anomaly....
Employing the Bonn–Gatchina partial wave analysis framework (PWA), we have analyzed HADES data of reaction p(3.5GeV)+p→pK+Λ. This might contain information about kaonic cluster "ppK−" (with quantum numbers JP=0− and total isospin I=1/2) via its decay into pΛ. Due to interference effects in our coherent description data, a hypothetical K‾NN (or, specifically "ppK−") signal need not necessarily show up as pronounced feature (e.g. peak) an invariant mass spectrum like Our PWA includes variety...
We present an analysis of proton number fluctuations in $\sqrt{s_{NN}}$ = 2.4 GeV Au+Au collisions measured with the High-Acceptance DiElectron Spectrometer (HADES) at GSI. With help extensive detector simulations done IQMD transport model events including nuclear clusters, various nuisance effects influencing observed cumulants have been investigated. Acceptance and efficiency corrections applied as a function fine grained rapidity transverse momentum bins, well considering local track...
