- Large Scale Distribution of Ultra High Energy Cosmic Rays Detected at the Pierre Auger Observatory With Zenith Angles up to 80°Publication . Pierre Auger collaboration (481 authors); Abreu, Pedro; Andringa, Sofia; Assis, Pedro; Brogueira, Pedro; Cazon, Lorenzo; Conceição, Ruben; Diogo, Francisco; Espadanal, Joao; Gonçalves, Patrícia; Oliveira, Micael; Pimenta, Mário; Santo, Catarina E; Santos, Eva; Sarmento, Raul; Tomé, BernardoWe present the results of an analysis of the large angular scale distribution of the arrival directions of cosmic rays with energy above 4 EeV detected at the Pierre Auger Observatory including for the first time events with zenith angle between 60° and 80°. We perform two Rayleigh analyses, one in the right ascension and one in the azimuth angle distributions, that are sensitive to modulations in right ascension and declination, respectively. The largest departure from isotropy appears in the $E\gt 8$ EeV energy bin, with an amplitude for the first harmonic in right ascension $r_{1}^{\alpha }=(4.4\pm 1.0)\times {{10}^{-2}}$, that has a chance probability $P(\geqslant r_{1}^{\alpha })=6.4\times {{10}^{-5}}$, reinforcing the hint previously reported with vertical events alone.
- Collins and Sivers asymmetries in muonproduction of pions and kaons off transversely polarised protonsPublication . COMPASS collaboration (209 authors); Bordalo, P; Franco, C; Nunes, A S; Quaresma, M; Quintans, C; Ramos, S; Silva, L; Stolarski, MMeasurements of the Collins and Sivers asymmetries for charged pions and charged and neutral kaons produced in semi-inclusive deep-inelastic scattering of high energy muons off transversely polarised protons are presented. The results were obtained using all the available COMPASS proton data, which were taken in the years 2007 and 2010. The Collins asymmetries exhibit in the valence region a non-zero signal for pions and there are hints of non-zero signal also for kaons. The Sivers asymmetries are found to be positive for positive pions and kaons and compatible with zero otherwise.
