Online data handling and storage at the CMS experiment / Andre, Jean-marc Olivier (Fermilab) ; Andronidis, Anastasios (Ioannina U.) ; Behrens, Ulf (DESY) ; Branson, James (UC, San Diego) ; Chaze, Olivier (CERN) ; Demiragli, Zeynep (MIT) ; Dobson, Marc (CERN) ; Dupont, Aymeric (CERN) ; Erhan, Samim (UCLA) ; Gigi, Dominique (CERN) et al.
During the LHC Long Shutdown 1, the CMS Data Acquisition (DAQ) system underwent a partial redesign to replace obsolete network equipment, use more homogeneous switching technologies, and support new detector back-end electronics. The software and hardware infrastructure to provide input, execute the High Level Trigger (HLT) algorithms and deal with output data transport and storage has also been redesigned to be completely file- based.

Scalar Boson CMS Run 1 final results, prospectives for Run 2 (and HL-LHC) / Bendavid, Joshua Lorne (CERN) /CMS Collaboration
Results are presented for the main standard model Higgs boson channels from the CMS experiment at the LHC. Results in the $\tau\tau$ and $WW\rightarrow 2\ell 2\nu$ final states constitute standalone evidences, and results in the $H\rightarrow ZZ\rightarrow 4\ell$ and $\gamma \gamma$ final states constitute standalone observations.

A New Event Builder for CMS Run II / Albertsson, Kim (CERN) ; Andre, Jean-marc Olivier (Fermilab) ; Andronidis, Anastasios (Ioannina U.) ; Behrens, Ulf (DESY) ; Branson, James (UC, San Diego) ; Chaze, Olivier (CERN) ; Cittolin, Sergio (UC, San Diego) ; Darlea, Georgiana Lavinia (MIT) ; Deldicque, Christian (CERN) ; Dobson, Marc (CERN) et al.
The data acquisition system (DAQ) of the CMS experiment at the CERN Large Hadron Collider (LHC) assembles events at a rate of 100kHz, transporting event data at an aggregate throughput of 100GB/s to the high-level trigger (HLT) farm. The DAQ system has been redesigned during the LHC shutdown in 2013/14. [...]

Studies of Higgs Boson Properties in Future LHC Runs / Xie, Si (Caltech) /ATLAS and CMS Collaborations
As the LHC begins its Run 2 period, it will quickly become the first and only Higgs factory in the world. The unique nature of the Higgs boson demands careful and precision studies of its properties. [...]

Search for Dark Matter at CMS / Daci, Nadir (Vrije U., Brussels) /CMS Collaboration
The CMS collaboration searched for Dark Matter (DM) particles produced in pairs in proton-proton (pp) collisions performed by the LHC at a centre-of-mass energy of 8 TeV, corresponding to an integrated luminosity of 19.7 /fb. The following signatures were investigated a single boosted object and a significant transverse momentum imbalance; associated production of DM with a pair of top quarks; decay of a Higgs boson (H) into a pair of DM particles.

Searches for weakly produced SUSY at LHC / Folgueras, Santiago (Oviedo U.) /ATLAS and CMS Collaborations
A summary of the different searches for weakly produced SUSY by both CMS and ATLAS is presented here. A review on the methodology of these searches, including event selection, background suppression and estimation methods, etc is covered. [...]

Open access to high-level data and analysis tools in the CMS experiment at the LHC / Calderon Tazon, Alicia (Cantabria Inst. of Phys.) ; Colling, David (Imperial Coll., London) ; Huffman, Michael Adam James (Imperial Coll., London) ; Lassila-Perini, Katri (Helsinki Inst. of Phys.) ; McCauley, Thomas (Notre Dame U.) ; Rao, Achintya Mahesh (West England U.) ; Rodriguez Marrero, Ana Yaiza (Cantabria Inst. of Phys.) ; Sexton-Kennedy, Elizabeth (Fermilab) /CMS Collaboration
The CMS experiment, in recognition of its commitment to datapreservation and open access as well as to education and outreach, hasmade its first public release of high-level data up to half of theproton-proton collision data at 7 TeV from 2010 in CMS Analysis ObjectData format. CMS has prepared, in collaboration with CERN and theother LHC experiments, an open data web portal based on Invenio. [...]

Study of Higgs production in fermionic decay channels at the LHC / Nayak, Aruna Kumar (DESY) /ATLAS and CMS Collaborations
The results of the searches for a Higgs boson decaying to down-type fermions are presented using the proton-proton collision data collected by the ATLAS and CMS experiments at the LHC, at a centre-of-mass energy of 7 and 8 TeV. The results obtained with the available data provides a strong evidence for a Higgs boson coupling to fermions. [...]
