Exploring the Phase Space of Jet Splittings at ALICE using Grooming and Recursive Techniques

KARASU UYSAL, Ayben | ALICE Collaboration

Hard splittings in the evolution of a hard scattered parton may be modified by the presence of a dense strongly interacting medium. Grooming procedures can be used to isolate such hard components of a jet and allows one to focus on the two subjets resulting from a sufficiently hard partonic splitting. Measurements of the symmetry parameter (z(g)), angular separation (R-g) and number of splittings (n(SD)) of Soft Drop groomed jets are reported as measured with the ALICE Detector in pp and Pb-Pb collisions at root s = 7 TeV and root s(NN) = 2.76 TeV, respectively. The use of recursive splittings ...Daha fazlası

Dielectron measurements in pp and Pb-Pb colllisions with ALICE at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

The production of low-mass dielectrons is one of the most promising tools for the investigation of chiral symmetry restoration and thermal radiation from the QGP created in heavy-ion collisions. To single out the signal characteristics of the QGP, it is crucial to understand the primordial e+e− pair production in vacuum, i.e. in inelastic proton-proton (pp) collisions. Low-mass dielectrons have been measured with ALICE at the LHC in pp collisions at √s = 7 and 13 TeV, and in Pb–Pb collisions at √sNN = 2.76 TeV. An overview of the results on dielectron production is presented, together with the ...Daha fazlası

Constraining production models with light (anti-)nuclei measurements in small systems with ALICE at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

The production of deuterons and anti-deuterons in pp collisions at root s = 7 and 13 TeV has been studied as a function of charged-particle multiplicity using the ALICE detector at the LHC. The preliminary results are shown here, together with those obtained in heavy-ion collisions. They are presented by focusing the discussion on the comparison with expectations from hadron-coalescence models.

Relationship of modernism, postmodernism and reflections of it on education

KAHRAMAN, Ayşe Derya

Making Modernism and Postmodernism a different sense of social life caused creation of different life and thinking styles. Modernism as a result of enlightening after the 18th century has taken its place in every area of the society. Post modern word has been defined as the further level of modernism. Every two kind of thinking styles have been effective at every point of life, also it affected education. Main elements of modern culture and postmodern education are combined and are being integrated with educational programs. The relationship of modernism and postmodernism is being examined sin ...Daha fazlası

Science and nature perception in the images and pictures of the children

YILMAZ, Fatih | KAHRAMAN, Ayşe Derya

The aim of this research is to search the perception of elementary school fourth grade students related to science and nature concept in artistic statements based on written descriptions related to their pictures and only pictures. The pictural and literal statements of the students related to science and nature have been examined based on this aim. The research has been realized at Diyarbakir, Kayapinar province Hantepe Egitim Sehitleri Elementary School and Ankara, Cankaya Province Sokullu Mehmet Pasa Elementary School in 2013-2014 semestr of educational period. 32 of students are having edu ...Daha fazlası

Event-shape- and multiplicity-dependent identified particle production in pp collisions at 13 TeV with ALICE at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

Multiplicity-dependent measurements of identified particle production led to the discovery of collective-like behavior in pp collisions at the LHC. Better understanding of the effects attributed to well-understood physics, like multiple hard scatterings, is required to establish whether this behaviour is truly collective in origin. Experimentally, those effects can be controlled using event shapes, like transverse spherocity, which allows the classification of pp collisions either as jetty or isotropic events. The transverse momentum (p(T)) spectra of light-flavor hadrons in pp collisions meas ...Daha fazlası

Testing the system size dependence of hydrodynamical expansion and thermal particle production with π, K, p, and φ in Xe–Xe and Pb–Pb collisions with ALICE

KARASU UYSAL, Ayben | ALICE Collaboration

We present new results on transverse momentum spectra, integrated yields, and mean transverse momenta of pions, kaons, and protons, as well as of phi-mesons for various centrality classes measured in Pb-Pb and Xe-Xe collisions at the LHC. This unique set of data allows us to investigate bulk particle production for very different systems at similar multiplicities. The chemical and kinetic freeze-out parameters are extracted via statistical-thermal and combined blast-wave fits to the data in heavy-ion collisions and are compared to results obtained in pp and p-Pb collisions at similar multiplic ...Daha fazlası

Measurements of anisotropic flow and flow fluctuations in Xe–Xe and Pb–Pb collisions with ALICE

KARASU UYSAL, Ayben | ALICE Collaboration

Anisotropic flow is a key observable to characterise the system created in heavy-ion collisions, as it is sensitive to the system's initial state, transport properties, the equation of state and freeze-out conditions. In these proceedings we present the anisotropic flow coefficients of inclusive charged particles in Pb-Pb collisions at root s(NN) = 2.76 and 5.02 TeV, and in Xe-Xe collisions at root s(NN) = 5.44 TeV. The results are reported for a wide range of particle transverse momentum within the pseudo-rapidity range vertical bar eta vertical bar < 0.8 at different collision centralities. ...Daha fazlası

Real-time data processing in the ALICE High Level Trigger at the LHC

KARASU UYSAL, Ayben | ALICE Collaboration

At the Large Hadron Collider at CERN in Geneva, Switzerland, atomic nuclei are collided at ultra-relativistic energies. Many final-state particles are produced in each collision and their properties are measured by the ALICE detector. The detector signals induced by the produced particles are digitized leading to data rates that are in excess of 48 GB/s. The ALICE High Level Trigger (HLT) system pioneered the use of FPGA- and GPU-based algorithms to reconstruct charged-particle trajectories and reduce the data size in real time. The results of the reconstruction of the collision events, availa ...Daha fazlası

Open heavy-flavour production and elliptic flow in p-Pb collisions at the LHC with ALICE

KARASU UYSAL, Ayben | ALICE Collaboration

Measurements of open heavy flavour production in p-A collisions allow the investigation of Cold Nuclear Matter effects. In addition, they are an important tool for a complementary investigation of the long-range correlations found in small systems in the light flavour sector. In this work, production measurements of D mesons at mid-rapidity in p-Pb collisions at root S-NN = 5.02 TeV are reported. Production yields are also reported for the heavy-flavour hadron decay electrons at central rapidity at root(SNN) = 5.02 and 8.16 TeV. The elliptic flow (nu(2)) of heavy-flavour hadron decay electrons ...Daha fazlası
