BEGIN:VCALENDAR VERSION:2.0 PRODID:-//CERN//INDICO//EN BEGIN:VEVENT SUMMARY:Forward-backward correlations between intensive observables DTSTART;VALUE=DATE-TIME:20161013T121500Z DTEND;VALUE=DATE-TIME:20161013T124500Z DTSTAMP;VALUE=DATE-TIME:20260814T151601Z UID:indico-contribution-69-775@cern.ch DESCRIPTION:Speakers: Vladimir Kovalenko (Saint Petersburg State Universit y)\nWe demonstrate that the investigations of the forward-backward correla tions between intensive observables enable to obtain more clear signal abo ut the initial stage of hadronic interaction\, e.g. about the process of s tring fusion\, compared to usual forward-backward multiplicity correlation s. As an example the correlation between mean-event transverse momenta of charged particles in separated rapidity intervals is considered. We show t hat this type of correlation is robust against the volume fluctuations and the details of the centrality determination.\n\nThe calculations are fulf illed both in the simple model with string fusion by introducing a lattice in transverse plane and in the framework of dipole-based Monte Carlo stri ng fusion model. The dependence of the correlation strength on the collisi on centrality is obtained for different initial energies. It is shown that at LHC energy the dependence reveals the decline of the correlation coeff icient for most central collisions and Pb-Pb\, reflecting the attenuation of color field fluctuations due to the string fusion at large string densi ty. This non-monotonic behavior with centrality is achieved only in heavy ion collisions at LHC\, while in Au-Au collisions at RHIC and p-Pb at LHC the string density is not enough to provide a decline of the correlation c oefficient for most central collisions. We compare the results both with t he ones obtained in alternative models and with the ones obtained by us us ing various MC generators.\n\nWe conclude that this type of correlation is promising for the observation of the signatures of string fusion and for detailed study of the initial stage of hadronic interaction in relativist ic heavy ion collisions at LHC energy.\n\nThe work was supported by the RF BR grant 15-02-02097-a and the Saint-Petersburg State University grant 11. 38.197.2014.\n\nhttps://indico.particle.mephi.ru/event/4/contributions/775 / LOCATION:Milan Hotel Hall of the 2nd floor URL:https://indico.particle.mephi.ru/event/4/contributions/775/ END:VEVENT BEGIN:VEVENT SUMMARY:Track reconstruction in the inhomogeneous magnetic field for Verte x Detector of NA61/SHINE experiment at CERN SPS DTSTART;VALUE=DATE-TIME:20161013T121500Z DTEND;VALUE=DATE-TIME:20161013T124500Z DTSTAMP;VALUE=DATE-TIME:20260814T151601Z UID:indico-contribution-69-758@cern.ch DESCRIPTION:Speakers: Anastasia Merzlaya (Saint-Petersburg State Universit y)\nThe heavy-ion programme of the NA61/SHINE experiment at CERN SPS is ex panding to allow precise measurements of exotic particles with short lifet ime. Vertex Detector for open charm measurements at the SPS is being const ructed by the NA61/SHINE Collaboration to meet the challenges of high spat ial resolution of secondary verticies and efficiency of track registration .

The main goal of the experiment includes studying the onset of deconfinement and searching for the critical point of strongly interac ting matter. It is of crucial importance to have a precise characterizati on of the event class with the PSD for the analysis of event-by-event obse rvables.\n The PSD has been already used for centrality selection on trig ger level in measurements of Be+Be and Ar +Sc reactions at beam energies 13 – 158 AGeV and Pb+Pb reaction at beam energy 30AGeV.\n In 2016\, the central modules of PSD have been equipped with new Hamamatsu MPPC silicon photodetectors in order to extend dynamic range for studying Pb+Pb reacti on at the full energy range (13 – 158 AGeV). Results of the PSD response on proton and lead beams will be presented.\n\nhttps://indico.particle.me phi.ru/event/4/contributions/646/ LOCATION:Milan Hotel Hall of the 2nd floor URL:https://indico.particle.mephi.ru/event/4/contributions/646/ END:VEVENT BEGIN:VEVENT SUMMARY:Forward hadron calorimeter (FHCAL) at MPD/NICA. DTSTART;VALUE=DATE-TIME:20161013T121500Z DTEND;VALUE=DATE-TIME:20161013T124500Z DTSTAMP;VALUE=DATE-TIME:20260814T151601Z UID:indico-contribution-69-641@cern.ch DESCRIPTION:Speakers: Sergey Morozov (INR/MEPhI)\nForward hadron calorimet er (FHCAL) is intended for the measurements of the geometry of heavy ions collisions. The main purpose of the FHCAL is to provide an experimental me asurement of a heavy-ion collision centrality and orientation of its react ion plane. Precise event-by-event estimate of these basic observables is c rucial for many physics phenomena studies to be performed by the MPD exper iment. \n\nFHCAL consists of two identical left/right arms placed at the d istance of about 3.2 meters from the beam collision point. This is a compe nsating lead-scintillator calorimeter designed to measure the energy distr ibution of the projectile nuclei fragments (spectators) and forward going particles produced close to the beam rapidity. The main design requirement s of the FHCAL are (a) forward rapidity coverage and sufficient energy res olution to allow for precise collision centrality determination and conseq uently of the number of participating nucleons and (b) granularity in the plane transverse to the beam direction which is needed for the reaction pl ane reconstruction. The proposed modular design of the FHCAL covers large transverse area around the beam spot position such that most of the projec tile spectator fragments deposit their energy in the FHCAL.\n\nThe expecte d FHCAL centrality resolution is below 10% for the most parts of the event s\, excluding the most central ones\, where the internal fluctuation of th e number of spectators is significant. At the same time\, the proper trans verse segmentation and the energy resolution of FHCAL ensures the reconstr uction of the event plane orientation with the accuracy of about $30^{0}$. \n\nhttps://indico.particle.mephi.ru/event/4/contributions/641/ LOCATION:Milan Hotel Hall of the 2nd floor URL:https://indico.particle.mephi.ru/event/4/contributions/641/ END:VEVENT BEGIN:VEVENT SUMMARY:Linear modulators on the monitor screen DTSTART;VALUE=DATE-TIME:20161013T121500Z DTEND;VALUE=DATE-TIME:20161013T124500Z DTSTAMP;VALUE=DATE-TIME:20260814T151601Z UID:indico-contribution-69-627@cern.ch DESCRIPTION:Speakers: Andrei Kobylyatskiy (National Research Nuclear Unive rsity «MEPhI» (MEPhI))\nThe simulation software to research the work of the linear modulator with the discharge line on the thyratron (generator w ith a soft switch) is presented.

It is practically impossible to give detail ed description of\nmagnetogram morphology. This is why signatures are quit e often used: critical points\, neutral lines\,\nunsigned and signed areas of magnetic textures. However\, when comparing two magnetograms adjacent in\ntime\, it is difficult to find or evaluate significant signature chang es because of high patterns\nvariability. This is why it is more convenien t to use approximating simplicial structures like\ngraphs\, namely set of vertices connected by edges.\n\nWe compute so-called critical nets\, which consist of stable minima and maxima points connected by\nascending paths in terms of Morse theory. Critical net approximates singular manifold of\n AR with graph which is rebuilt during evolution. Dynamics regimes can be c onveniently tracked using\nmethods of spectral geometry. For that we use d iscrete laplacian and its spectrum.
