Miksi Varkaus oli menestyvä urheilukaupunki 1960-luvulla?
2018
Urheilumenestyksen tarkastelussa painopiste on ollut maittain toteutetussa joukkueiden, seurojen ja yksilöurheilijoiden menestyksen vertailussa. Sen sijaan paikkakuntien urheilumenestystä on tutkimuksissa vertailtu vähemmän. Tutkimuksessa jäljitettiin millaista menestystä varkautelaiset urheilijat saavuttivat 1960-luvulla ja mitkä tekijät vaikuttivat paikalliseen urheilumenestykseen? Varkautelainen urheilumenestys suhteutettiin 11 muuhun vastaavankokoiseen kaupunkiin. Tutkimuksemme sijoittuu historiallis-sosiologisen tapaus- ja rakennetutkimuksen piiriin. Tällöin tunnistamme paikallisia toimijaverkostoja sekä yhteiseen tekemiseen sitovia taloudellisia, poliittisia ja kulttuurisia tekijöitä.…

Direct observation of the dead-cone effect in quantum chromodynamics.
2022
In particle collider experiments, elementary particle interactions with large momentum transfer produce quarks and gluons (known as partons) whose evolution is governed by the strong force, as described by the theory of quantum chromodynamics (QCD)1. These partons subsequently emit further partons in a process that can be described as a parton shower2, which culminates in the formation of detectable hadrons. Studying the pattern of the parton shower is one of the key experimental tools for testing QCD. This pattern is expected to depend on the mass of the initiating parton, through a phenomenon known as the dead-cone effect, which predicts a suppression of the gluon spectrum emitted by a he…
Measurement of the Groomed Jet Radius and Momentum Splitting Fraction in pp and Pb-Pb Collisions at √sNN = 5.02 TeV
2022
This article presents groomed jet substructure measurements in pp and Pb−Pb collisions at √sNN = 5.02 TeV with the ALICE detector. The soft drop grooming algorithm provides access to the hard parton splittings inside a jet by removing soft wide-angle radiation. We report the groomed jet momentum splitting fraction, zg, and the (scaled) groomed jet radius, θg. Charged-particle jets are reconstructed at midrapidity using the anti-kT algorithm with resolution parameters R=0.2 and R=0.4. In heavy-ion collisions, the large underlying event poses a challenge for the reconstruction of groomed jet observables, since fluctuations in the background can cause groomed parton splittings to be misidentif…
Sapieżyńska ochrona dóbr Potockich w starostwie owruckim w latach 80. i 90. XVII wieku Przyczynek do badań nad współpracą rodzin magnackich w czasach…
2019
The Sapiehas and the Potockis were amongst the most influential families of the Polish‑Lithuanian Commonwealth. The latter family owned numerous estates in Ukraine, which were directly under threat from marching Lithuanian soldiers. Kazimierz Jan Sapieha, Grand Hetman of Lithuania was in charge of the said estates. Due to cooperation of the two magnate families, he attempted to shield the Potockis’ estates and possessions from Lithuanian troops marching to or returning from the war with Turkey. To that aim he utilised legal proclamations called Universals. The Potockis returned the favour by entering into political collaboration. Hetman Kazimierz Jan Sapieha, having been absent from the Sie…
Spectral function for overoccupied gluodynamics from real-time lattice simulations
2018
We study the spectral properties of a highly occupied non-Abelian non-equilibrium plasma appearing ubiquitously in weak coupling descriptions of QCD matter. The spectral function of this far-from-equilibrium plasma is measured by employing linear response theory in classical-statistical real-time lattice Yang-Mills simulations. We establish the existence of transversely and longitudinally polarized quasiparticles and obtain their dispersion relations, effective mass, plasmon frequency, damping rate and further structures in the spectral and statistical functions. Our new method can be interpreted as a non-perturbative generalization of hard thermal loop (HTL) effective theory. We see indica…
Production of Λ and KS0 in jets in p–Pb collisions at √sNN = 5.02 TeV and pp collisions at √s = 7 TeV
2022
The production of Λ baryons and KS0 mesons (V0 particles) was measured in p–Pb collisions at √sNN=5.02 TeV and pp collisions at √s=7 TeV with ALICE at the LHC. The production of these strange particles is studied separately for particles associated with hard scatterings and the underlying event to shed light on the baryon-to-meson ratio enhancement observed at intermediate transverse momentum (pT) in high multiplicity pp and p–Pb collisions. Hard scatterings are selected on an event-by-event basis with jets reconstructed with the anti-kT algorithm using charged particles. The production of strange particles associated with jets pT,jetch>10 and pT,jetch>20 GeV/c in p–Pb collisions, and with …
General balance functions of identified charged hadron pairs of (π,K,p) in Pb–Pb collisions at √sNN = 2.76 TeV
2022
First measurements of balance functions (BFs) of all combinations of identified charged hadron (π,K,p) pairs in Pb−Pb collisions at √sNN = 2.76 TeV recorded by the ALICE detector are presented. The BF measurements are carried out as two-dimensional differential correlators versus the relative rapidity (Δy) and azimuthal angle (Δφ) of hadron pairs, and studied as a function of collision centrality. The Δφ dependence of BFs is expected to be sensitive to the light quark diffusivity in the quark−gluon plasma. While the BF azimuthal widths of all pairs substantially decrease from peripheral to central collisions, the longitudinal widths exhibit mixed behaviors: BFs of ππ and cross-species pairs…
Spectral function of fermions in a highly occupied non-Abelian plasma
2022
We develop a method to obtain fermion spectral functions non-perturbatively in a non-Abelian gauge theory with high occupation numbers of gauge fields. After recovering the free field case, we extract the spectral function of fermions in a highly occupied non-Abelian plasma close to its non-thermal fixed point, i.e., in a self-similar regime of the non-equilibrium dynamics. We find good agreement with hard loop perturbation theory for medium-induced masses, dispersion relations and quasiparticle residues. We also extract the full momentum dependence of the damping rate of the collective excitations.
Massive quarks in NLO dipole factorization for DIS : Transverse photon
2022
We calculate the light cone wave functions for the QCD Fock components in a transverse virtual photon necessary for applications at next-to-leading order in the QCD coupling, including quark masses. We present a detailed calculation of both the one loop wave function for the quark-antiquark Fock component and the tree level wave function for the quark-antiquark-gluon Fock component. The quark masses are renormalized in the pole mass scheme, satisfying constraints from the requirement of Lorentz invariance. In particular the quark Pauli form factor at NLO is recovered from the on-shell limit of the quark-antiquark Fock component. We use our result to calculate the next-to-leading order corre…
