Measurement of charged particle spectra in minimum-bias events from proton-proton collisions at root s =13 TeV

Pseudorapidity, transverse momentum, and multiplicity distributions are measured in the pseudorapidity range vertical bar eta vertical bar 0.5 GeV in proton-proton collisions at a center-of-mass energy of root s = 13 TeV. Measurements are presented in three different event categories. The most inclusive of the categories corresponds to an inelastic pp data set, while the other two categories are exclusive subsets of the inelastic sample that are either enhanced or depleted in single diffractive dissociation events. The measurements are compared to predictions from Monte Carlo event generators used to describe high-energy hadronic interactions in collider and cosmic-ray physics.Peer reviewe

Conditional cash transfer programmes: the recent experience in Latin America and the Caribbean

Includes BibliographySpanish version available at the LibraryForeword Alicia BárcenaThis document summarizes experience with conditional cash transfer or "co-responsibility" (CCT) programmes in Latin America and the Caribbean, over a period lasting more than 15 years. During this time, CCTs have consolidated and spread through the region's various countries as a tool of choice for poverty-reduction policy. This document, which it is hoped will serve as a basis and input for discussion and progress in building social-protection systems premised on inclusion and universal rights, provides detailed information on the different components of CCTs. It also reviews their main characteristics in terms of the definition and registration of programme users, the targeting mechanisms used, the various types of benefits provided, and the conditionalities attached to them. It then analyses the historical trend of the indicators of CCT investment and coverage, and the information available 8 ECLAC on their effects in different domains. Lastly, it makes an assessment of the experience and the main challenges that these programmes pose in terms of their sustainability, legal framework, accountability, participation, institutionality and inter-sectoral characteristics
