   Multidimensional analysis of Bose-Einstein correlations in pp collisions at 2.76 and 7 TeV in CMS

   Sandra S. Padula (for the CMS Collaboration)🇧🇷

   Multidimensional two-particle Bose-Einstein correlation functions of charged hadrons are reported for pp collisions at 2.76 and 7 TeV in terms of different components of the pair relative momentum, extending the previous one-dimensional (1-D) analyses of CMS. This allows for investigating the extension of the source accessible to the femtoscopic correlation technique in different directions, revealing a more detailed picture of the emitting source in these collisions at increasing energies. The measurements are performed for different intervals of the pair average transverse momentum, kT, and for increasing charged particle multiplicitiy, Nch. Results in 1-D, 2-D and 3-D show a decrease of the fit radius parameters with kT, whereas a clear rise with Nch is observed in all cases. In addition, the fit radius parameters at both energies show close similarity in size and behavior within the same intervals of (Nch,kT).

   This document presents the recommendations and scientific conclusions from the Town Meeting on QCD and Hadronic Physics that took place in the period 13-15 September 2014 at Temple University as part of the NSAC 2014 Long Range Planning process. It highlights progress in hadron physics in the seven years since the 2007 Long Range Plan (LRP07), and presents a vision for the future by identifying key questions and plausible paths to solutions which should define our next decade. In defining the priority of outstanding physics opportunities for the future, both prospects for the short (roughly 5 years) and longer term (beyond 10 years) are identified together with the facilities, personnel and other resources needed to maximize the discovery potential in hadronic physics worldwide. In this connection, the potential of an electron ion collider is highlighted.
