Tsallis Fits to pT Spectra for pp Collisions at the LHC
نویسندگان
چکیده
Phenomenological Tsallis fits to the CMS and ATLAS transverse spectra of charged particles were found to extend for pT from 0.5 to 181 GeV in pp collisions at the LHC at √ s = 7 TeV, and for pT from 0.5 to 31 GeV at √ s = 0.9 TeV. The simplicity of the Tsallis parametrization and the large range of the fitting transverse momentum raise questions on the physical meaning of the degrees of freedom that enter into the Tsallis distribution or q-statistics.

Tsallis fits to pT spectra and multiple hard scattering in pp collisions at the LHC
Phenomenological Tsallis fits to the CMS, ATLAS, and ALICE transverse momentum spectra of hadrons for pp collisions at LHC were recently found to extend over a large range of the transverse momentum. We investigate whether the few degrees of freedom in the Tsallis parametrization may arise from the relativistic parton-parton hard-scattering and related processes. The effects of the multiple har...
متن کاملLarge Transverse Momenta and Tsallis Thermodynamics
The charged particle transverse momentum (pT ) spectra measured by the ATLAS and CMS collaborations in proton proton collisions at √ s = 0.9 and 7 TeV have been studied using Tsallis thermodynamics. A thermodynamically consistent form of the Tsallis distribution is used for fitting the transverse momentum spectra at mid-rapidity. It is found that the fits based on the proposed distribution prov...

As a complementary study to that performed on the transverse momentum (pT) spectra of pions, kaons and protons in proton-proton (pp) collisions at LHC energies 0.9, 2.76 and 7 TeV, we present a scaling behaviour in the pT spectra of strange particles (K 0 S , Λ and Ξ) at these three energies. This scaling behaviour is exhibited when the spectra are expressed in a suitable scaling variable z = p...
متن کاملhigh-pT hadron spectra in nearly central Pb+Pb collisions at the LHC
We study the hadron spectra in nearly central A+A collisions at RHIC and LHC in a broad transverse momentum range. We cover the low-pT spectra using longitudinally boost-invariant hydrodynamics with initial energy and net-baryon number densities from the perturbative QCD (pQCD)+saturation model. Build-up of the transverse flow and sensitivity of the spectra to a single decoupling temperature Td...
