Many measurements and searches for physics beyond the standard model at the LHC rely on the efficient identification of heavy-flavour jets, i.e. jets originating from bottom or charm quarks. In this paper, the discriminating variables and the algorithms used for heavy-f...

For the first time a principle-component analysis is used to separate out different orthogonal modes of the two-particle correlation matrix from heavy ion collisions. The analysis uses data from √s[subscript NN] = 2.76 TeV PbPb and √s[subscript NN] = 5.02 TeV pPb collis...

Charge-dependent azimuthal correlations of same- and opposite-sign pairs with respect to the second- and third-order event planes have been measured in pPb collisions at √sNN=8.16TeV and PbPb collisions at 5.02 TeV with the CMS experiment at the LHC. The measurement is ...

The DESIR Winter School "Shaping new approaches to data management in arts and humanities" took place in Lisbon on 10-13 December 2019. The event was hosted by NOVA FCSH University facilities and was organised in the framework of the Horizon 2020 funded project DESIR (D...

SPAKE2 is a balanced password-authenticated key exchange (PAKE) protocol, proposed by Abdalla and Pointcheval at CTRSA 2005. Due to its simplicity and efficiency, SPAKE2 is one of the balanced PAKE candidates currently under consideration for standardization by the CFRG...

The CMS apparatus was identified, a few years before the start of the LHC operation at CERN, to feature properties well suited to particle-flow (PF) reconstruction: a highly-segmented tracker, a fine-grained electromagnetic calorimeter, a hermetic hadron calorimeter, a ...

A search is performed for anomalous interactions of the recently discovered Higgs boson using matrix element techniques with the information from its decay to four leptons and from associated Higgs boson production with two quark jets in either vector boson fusion or as...

The European Commission aims to develop a more sustainable environment for research infrastructures ecosystem, and to ensure that the benefits and impacts are widely perceived by research communities and led to research excellence. This vision is reflected in a range of...

A search for low mass narrow vector resonances decaying into quark-antiquark pairs is presented. The analysis is based on data collected in 2017 with the CMS detector at the LHC in proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to an integr...

Client-side apps (e.g., mobile or in-browser) need cloud data to be available in a cache, for both reads and updates. The cache should use resources sparingly, be consistent and fault-tolerant. The system needs to scale to high numbers of unreliable and resource-poor cl...
