      Aad, Georges; Buanes, Trygve; Burgess, Thomas; Eigen, Gerald; Johansen, Lars Gimmestad; Kastanas, Alex; Lipniacka, Anna; Mohn, Bjarte Alsaker; Øye, Ola Kristoffer; Sandaker, Heidi; Sjursen, Therese; Stugu, Bjarne; Tonoyan, Arshak; Ugland, Maren; Zutshi, V. (Peer reviewed; Journal article, 2010-04)
      The first measurements from proton-proton collisions recorded with the ATLAS detector at the LHC are presented. Data were collected in December 2009 using a minimum-bias trigger during collisions at a centre-of-mass energy ...

      The inclusive charged particle transverse momentum distribution is measured in proton-proton collisions at \(\sqrt{s} = 900\)~GeV at the LHC using the ALICE detector. The measurement is performed in the central pseudorapidity ...
