Long-distance structured laser beams created by optical aberrations / Sulc, Miroslav (Liberec Tech. U. ; Prague, Inst. Plasma Phys.) ; Gayde, Jean-Christophe (CERN) ; Polak, Krystof (Liberec Tech. U. ; CERN)
A novel approach to creating long-range Structured Laser Beams (SLB) using optical aberrations is described. By combining optical elements that produce significant spherical and defocus aberrations, it is possible to generate an interference field with both transverse and longitudinal local polarization. [...]

3D Polarisation of a Structured Laser Beam and Prospects for its Application to Charged Particle Acceleration / Polak, K (CERN ; Liberec Tech. U.) ; Gayde, J C (CERN) ; Sulc, M (Liberec Tech. U. ; Prague, Inst. Plasma Phys.)
A Structured Laser Beam (SLB) is a type of optical beam with spatially inhomogeneous 3D polarisation structures. Generating SLBs from vector beams allows the creation of Hollow Structured Laser Beams (HSLB) with a dark central core. [...]

Analysis of centroiding algorithms for non-diffracting structured and hollow structured laser beams / Dusek, Martin (CERN ; Liberec Tech. U.) ; Roikova, Eva (CERN ; Liberec Tech. U.) ; Mergelkuhl, Dirk ; Gayde, Jean-Christophe (CERN) ; Polak, Krystof (CERN) ; Polak, Krystof (Liberec Tech. U.) ; Sulc, Miroslav (Liberec Tech. U.) ; Sulc, Miroslav (Prague, Inst. Plasma Phys.)
This paper explores the potential of optical-based systems, specifically pseudo-non-diffractive beams, as an alternative for alignment. The study focuses on structured laser beams and hollow structured laser beams, which exhibit lower divergence and enhanced detection capabilities. [...]

Variation of structured laser beam pattern and optimization for an alignment reference line creation / Niewiem, Witold (Zurich, ETH) ; Niewiem, Witold (CERN) ; Polak, Krystof (CERN) ; Polak, Krystof (Liberec Tech. U.) ; Dusek, Martin (CERN) ; Dusek, Martin (Liberec Tech. U.) ; Mergelkuhl, Dirk (CERN) ; Gayde, Jean-Christophe (CERN) ; Wieser, Andreas (Zurich, ETH) ; Sulc, Miroslav (Liberec Tech. U.) et al.
The alignment of particle accelerators demands a dedicated measurement system based on a straight-line reference. This straight line can be provided by a laser beam. [...]

The potential contribution of a structured laser beam to accelerator alignment technology / Gayde, Jean-Christophe (CERN) ; Dusek, Martin (CERN ; Liberec Tech. U.) ; Mergelkuhl, Dirk (CERN) ; Niewiem, Witold (CERN ; Zurich, ETH) ; Polak, Krystof (CERN ; Liberec Tech. U.) ; Roiková, Eva (Liberec Tech. U.) ; Sulc, Miroslav (Liberec Tech. U. ; Prague, Inst. Plasma Phys.)
The Structured Laser Beam (SLB) is a type of optical beam characterized by an intense, sharply defined, low divergence core at its center, similar in its transverse intensity distribution to a Bessel beam. The SLB can propagate over a theoretically infinite distance, and has recently been tested up to a distance of 900 m. [...]

Multiplicity dependence of two-particle azimuthal correlations in pp collisions at the LHC / ALICE Collaboration
We present the measurements of particle pair yields per trigger particle obtained from di-hadron azimuthal correlations in pp collisions at $\sqrt{s}$=0.9, 2.76, and 7 TeV recorded with the ALICE detector. The yields are studied as a function of the charged particle multiplicity. [...]

Directed flow of charged particles at mid-rapidity relative to the spectator plane in Pb-Pb collisions at $\sqrt{s_{NN}}$=2.76 TeV / ALICE Collaboration
The directed flow of charged particles at midrapidity is measured in Pb-Pb collisions at $\sqrt{s_{NN}}$=2.76 TeV relative to the collision plane defined by the spectator nucleons. Both, the rapidity odd ($v_1^{odd}$) and even ($v_1^{even}$) directed flow components are reported. [...]
