title: "Table 10" of "Charged particle nuclear modification factor and pseudorapidity asymmetry in pPb collisions at sqrt(sNN)=5.02 TeV with CMS"

description: Charged-particle forward-backward yield asymmetry.
description: CERN-LHC. Transverse momentum spectra of charged particles are measured by the CMS experiment at the CERN LHC in pPb collisions at sqrt(s[NN]) =5.02 TeV, in the range 0.4 &lt; pt &lt; 120 GeVc and pseudorapidity abs(eta[CM]) &lt; 1.8 in the proton-nucleon center-of-mass frame, with the convention that the incoming proton travels in the positive eta[CM] direction.

The charged particle yields reported in the tables are given as per double-sided event yields, where double-sided events are defined as a collision producing at least one particle in the pseudorapidity range -5 &lt; eta[LAB] &lt; -3 and another in the range 3 &lt; eta[LAB] &lt; 5, each with proper lifetime tau &gt; 10^-18 s and energy E &gt; 3 GeV (see See Eur.Phys.J. C74 (2014) 2847). The data are corrected for the finite bin-width effect. 

A pp reference spectrum at sqrt(s) = 5.02 TeV is obtained by interpolation from previous measurements at higher and lower center-of-mass energies, and is used to determine the nuclear modification factor for abs(eta[CM]) &lt; 1.0. Note that the uncertainty of 4.8 percent in the Glauber calculation of the nuclear thickness function, T_pPb, is not included in the total systematic uncertainty quoted in the table. 

The forward-backward asymmetry of the yields for A &lt; abs(eta[CM]) &lt; B is defined as the ratio of the differential charged particle yield integrated over the range -B &lt; eta[CM] &lt; -A (Pb-going side) to the differential charged particle yield integrated over the range A &lt; eta[CM] &lt; B (p-going side). This quantity is measured for three ranges: 0.3 &lt; abs(eta[CM]) &lt; 0.8, 0.8 &lt; abs(eta[CM]) &lt; 1.3, and 1.3 &lt; abs(eta[CM]) &lt; 1.8.

title: "Table 1" of "Transverse target spin asymmetries in exclusive $\rho^0$ muoproduction"

description: Single-spin azimuthal asymmetries for a transversely (T) polarised target and unpolarised (U) beam.
description: CERN-SPS-NA. Exclusive production of $\rho^0$ mesons was studied at the COMPASS experiment by scattering 160 GeV/$c$ muons off transversely polarised protons. Five single-spin and three double-spin azimuthal asymmetries were measured as a function of $Q^2$, $x_{Bj}$, or $p_{T}^{2}$. The $\sin \phi_S$ asymmetry is found to be $-0.019 \pm 0.008(stat.) \pm 0.003(syst.)$. All other asymmetries are also found to be of small magnitude and consistent with zero within experimental uncertainties. Very recent calculations using a GPD-based model agree well with the present results. The data is interpreted as evidence for the existence of chiral-odd, transverse generalized parton distributions.

title: "Table 1" of "Study of the Underlying Event at Forward Rapidity in pp Collisions at $\sqrt{s}$ = 0.9, 2.76, and 7 TeV"

description: Ratio of the energy deposited in the pseudorapidity range $-6.6 &lt; \eta &lt; -5.2$ for events with a charged-particle jet with $|\eta^\text{jet}| &lt; 2$ with respect to the energy in inclusive events, as a function of the jet transverse momentum $p_{\rm T}$ for $\sqrt{s} =$ 0.9, 2.76 , and 7 TeV. 
Data are taken from the Rivet Analysis.
description: CERN-LHC. The underlying event activity in proton-proton collisions at forward pseudorapidity $(-6.6 &lt; \eta &lt; -5.2)$ is studied with the CMS detector at the LHC, using a novel observable: the ratio of the forward energy density, $dE/d\eta$, for events with a charged-particle jet produced at central pseudorapidity $|\eta^{jet}| &lt; 2$ to the forward energy density for inclusive events. This forward energy density ratio is measured as a function of the central jet transverse momentum, pt, at three different pp centre-of-mass energies $\sqrt{s} =$ 0.9, 2.76, and 7 TeV. In addition, the $\sqrt{s}$ evolution of the forward energy density is studied in inclusive events and in events with a central jet. The results are compared to those of Monte Carlo event generators for pp collisions and are discussed in terms of the underlying event. Whereas the dependence of the forward energy density ratio on jet pt at each $\sqrt{s}$ separately can be well reproduced by some models, all models fail to simultaneously describe the increase of the forward energy density with $\sqrt{s}$ in both inclusive events and in events with a central jet.

title: "Table 1" of "Search for Displaced Supersymmetry in events with an electron and a muon with large impact parameters"

description: Electron transverse impact parameter distribution for data and expected background processes after the preselection requirements have been applied. The event yields per bin have been rescaled to account for the varying bin sizes. The rightmost bin contains the overflow entries.
description: CERN-LHC. A search for new long-lived particles decaying to leptons is presented using proton-proton collisions produced by the LHC at $\sqrt{s}$ = 8 TeV. Data used for the analysis were collected by the CMS detector and correspond to an integrated luminosity of 19.7 fb$^{-1}$. Events are selected with an electron and a muon that have transverse impact parameter values between 0.02 cm and 2 cm. The search has been designed to be sensitive to a wide range of models with non-prompt e-$\mu$ final states. Limits are set on the ''displaced supersymmetry'' model, with pair production of top squarks decaying into an e-$\mu$ final state via R-parity violating interactions. The results are the most restrictive to date on this model, with the most stringent limit being obtained for a top squark lifetime corresponding to $c\tau$ = 2 cm, excluding masses below 790 GeV at 95% confidence level.
