We summarize the state of the art of a program of UV observations from space of meteor phenomena, a secondary objective of the JEM-EUSO international collaboration. Our preliminary analysis indicates that JEM-EUSO, taking advantage of its large FOV and good sensitivity, should be able to detect meteors down to absolute magnitude close to 7. This

The CMS Collaboration presents the first measurement of the differential cross section of jets from charm quarks produced in proton-lead (pPb) collisions at a nucleon-nucleon center-of-mass energy of √{sNN} = 5.02TeV, as well as results from charm quark jets in proton-proton (pp) collisions at √{ s} = 2.76 and 5.02TeV. By comparing the yields of

A measurement of the t\overline{t} production cross section at √{s}=13 TeV is presented using proton-proton collisions, corresponding to an integrated luminosity of 2.2 fb-1, collected with the CMS detector at the LHC. Final states with one isolated charged lepton (electron or muon) and at least one jet are selected and categorized according to the

The discovery of an astrophysical flux of high-energy neutrinos by the IceCube Collaboration marks a major breakthrough in the ongoing search for the origin of cosmic rays. Presumably, the neutrinos, together with gamma rays, result from pion decay, following hadronic interactions of protons accelerated in astrophysical objects to ultra

La tacoclina solar situada en la base de la zona de convección es la capa de cizalladura que conecta la rotación diferencial en la envoltura convectiva y la rotación rígida en el interior radiativo. Generalmente se cree que alberga la localización de la dinamo solar y desempeña un importante papel en la generación y almacenamiento de los campos
