Connecting restricted, high-availability, or low-latency resources to a seamless Global Pool for CMS / Balcas, J (Caltech) ; Bockelman, B (Nebraska U.) ; Hufnagel, D (Fermilab) ; Hurtado Anampa, K (Notre Dame U.) ; Jayatilaka, B (Fermilab) ; Khan, F (NCP, Islamabad) ; Larson, K (Fermilab) ; Letts, J (UC, San Diego) ; Mascheroni, M (Fermilab) ; Mohapatra, A (Wisconsin U., Madison) et al. /CMS
The connection of diverse and sometimes non-Grid enabled resource types to the CMS Global Pool, which is based on HTCondor and glideinWMS, has been a major goal of CMS. These resources range in type from a high-availability, low latency facility at CERN for urgent calibration studies, called the CAF, to a local user facility at the Fermilab LPC, allocation-based computing resources at NERSC and SDSC, opportunistic resources provided through the Open Science Grid, commercial clouds, and others, as well as access to opportunistic cycles on the CMS High Level Trigger farm.

The CMS experiment at LHC will upgrade its forward muon spectrometer by incorporating Triple-GEM detectors. This upgrade referred to as GEM Endcap (GE1/1), consists of adding two back-to-back Triple-GEM detectors in front of the existing Cathode Strip Chambers (CSC) in the innermost ring of the endcap muon spectrometer.

R&D on a new type of micropattern gaseous detector: The Fast Timing Micropattern detector / CMS Collaboration
Micropattern gaseous detectors (MPGD) underwent significant upgrades in recent years, introducing resistive materials to build compact spark-protected devices. Exploiting this technology further, various features such as space and time resolution, rate capability, sensitive area, operational stability and radiation hardness can be improved. [...]

Measurements of the associated production of a Z boson and b jets in pp collisions at ${\sqrt{s}} = 8\,\text {TeV} $ / CMS Collaboration
Measurements of the associated production of a Z boson with at least one jet originating from a b quark in proton-proton collisions at $ \sqrt{s} = $ 8 TeV are presented. Differential cross sections are measured with data collected by the CMS experiment corresponding to an integrated luminosity of 19.8 fb$^{-1}$. [...]

Measurement of the mass difference between top quark and antiquark in pp collisions at $\sqrt{s} = 8$ TeV / CMS Collaboration
The invariance of the standard model (SM) under the CPT transformation predicts equality of particle and antiparticle masses. This prediction is tested by measuring the mass difference between the top quark and antiquark (Delta m[t] = m[t] - m[t-bar]) that are produced in pp collisions at a center-of-mass energy of 8 TeV, using events with a muon or an electron and at least four jets in the final state.

The CMS trigger system / CMS Collaboration
This paper describes the CMS trigger system and its performance during Run 1 of the LHC. The trigger system consists of two levels designed to select events of potential physics interest from a GHz (MHz) interaction rate of proton-proton (heavy ion) collisions. [...]

Measurement of electroweak production of a W boson and two forward jets in proton-proton collisions at $ \sqrt{s} = $ 8 TeV / CMS Collaboration
A measurement is presented of the cross section for the electroweak production of a W boson in association with two jets in proton-proton collisions at a center-of-mass energy of 8 TeV. The data set was collected with the CMS detector and corresponds to an integrated luminosity of 19.3 fb$^{-1}$. [...]

Search for lepton flavour violating decays of the Higgs boson to $\mathrm{ e }\tau$ and $\mathrm{ e }\mu$ in proton-proton collisions at $\sqrt{s}= $ 8 TeV / CMS Collaboration
A direct search for lepton flavour violating decays of the Higgs boson (H) in the $\mathrm{ H } \to \mathrm{ e } \tau$ and $\mathrm{ H } \to \mathrm{ e } \mu$ channels is described. The data sample used in the search was collected in proton-proton collisions at $\sqrt{s}= $ 8 TeV with the CMS detector at the LHC and corresponds to an integrated luminosity of 19.7 fb$^{-1}$.

Jet energy scale and resolution in the CMS experiment in pp collisions at 8 TeV / CMS Collaboration
Improved jet energy scale corrections, based on a data sample corresponding to an integrated luminosity of 19.7 fb$^{-1}$ collected by the CMS experiment in proton-proton collisions at a center-of-mass energy of 8 TeV, are presented. The corrections as a function of pseudorapidity $\eta$ and transverse momentum $p_{\mathrm{T}}$ are extracted from data and simulated events combining several channels and methods. [...]
