Emergence and Violation of Geometrical Scaling in pp Collisions
We argue that geometrical scaling (GS) proposed originally in the context of Deep Inelastic Scattering (DIS) at HERA works also in pp collisions at the LHC energies and in NA61/SHINE experiment. We show that in DIS GS is working up to relatively large Bjorken x ~ 0.1 . As a consequence negative pion multiplicity pT distributions at NA61/SHINE energies exhibit GS in mid rapidity region. For y ≠ ...
متن کاملQCD Scaling Violation at Small x
We investigate the evolution of parton densities at small values of the momentum fraction, x, by including resummed anomalous dimensions in the renor-malization group equations. The resummation takes into account the leading-logarithmic contributions (S ln x) k given by the BFKL equation and the next-to-leading-logarithmic corrections from quark evolution. We present numerical results for the p...
متن کاملA Geometrical Interpretation of Parity Violation in Gravity with Torsion
In a space-time with torsion, the action for the gravitational field can be extended with a parity-violating piece. We show how to obtain such a piece from geometry itself, by suitably modifying the affine connection so as to include a pseudo-tensorial part. A consistent method is thus suggested for incorporating parity-violation in the Lagrangians of all matter fields with spin in a space-time...
متن کاملScaling Violation and Gauge/String Duality
We explore the possibilities for scaling violation in gauge theories that have string duals. Like in perturbative QCD, short-distance behaviour yields logarithms that violate the scaling. PACS number(s): 11.25.Pm, 12.38.Bx LPTENS-05-40
متن کاملOn geometrical scaling of split-ring and double-bar resonators at optical frequencies
In this paper we consider the resonant frequency of split-ring resonators and double-bar resonators used to create artificial magnetic response at terahertz and optical frequencies. It is known that geometrical scaling of the resonant frequency of split rings breaks down at high frequencies (in the visible) due to electromagnetic properties of metals at those frequencies. Here we will discuss t...
