“…Finally, the soft component (string fragments) represents a longitudinal fragmentation in unlikesign pairs and produces a 1-dimensional Gaussian correlation centered at ∆η = 0. This 1-dimensional structure was observed also by other experiments [7][8][9] and is consistent with expectations from the low-mass resonance gas model [10], Monte Carlo model of isotropic decay of clusters [11], and local charge conservation (charge ordering) in longitudinally fragmenting strings [12], described in the string fragmentation model such as the Lund model [13][14][15][16].…”

Abstract. We report on the studies of two-particle angular correlations measured in proton-proton collisions at a center-of-mass energy of √ s = 7 TeV recorded by AL-ICE at the LHC. Two-particle correlations in relative azimuth (Δϕ) and pseudorapidity (Δη) are expected to exhibit several structures which arise from different physics mechanisms and allow us to study the wide landscape of correlations. The results include the dependence of the correlation function on the event multiplicity, the charge combination and species (pions, kaons or protons) of particles in the pair.

“…As this process again is of a gaussian character, we may use very similar methods to diagonalise it, cf. also [9]. There is, however, a small subtlety.…”

We will in this note show that it is possible to diagonalise the Lund Fragmentation Model. We show that the basic original result, the Lund Area law, can be factorised into a product of transition operators, each describing the production of a single particle and the two adjacent breakup points (vertex positions) of the string field. The transition operator has a discrete spectrum of (orthonormal) eigenfunctions, describing the vertex positions (which in a dual way corresponds to the momentum transfers between the produced particles) and discrete eigenvalues, which only depend upon the particle produced. The eigenfunctions turn out to be the well-known two-dimensional harmonic oscillator functions and the eigenvalues are the analytic continuations of these functions to time-like values (corresponding to the particle mass). In this way all observables in the model can be expressed in terms of analytical formulas. In this note only the 1 + 1-dimensional version of the model is treated but we end with remarks on the extensions to gluonic radiation, transverse momentum generation etc, to be performed in future papers. 1 bo@thep.lu.se 2 fredrik@thep.lu.se
