ANU BiH: Susreti mladih istraživača BiH iz STEM oblasti

 Susreti mladih istraživača Bosne i Hercegovine iz oblasti prirodnih, tehničkih i matematičkih nauka (STEM) održani su 3. i 4. novembra 2023. godine u organizaciji Odjeljenja tehničkih nauka Akademije nauka i umjetnosti Bosne i Hercegovine i u saradnji s Federalnim ministarstvom obrazovanja i nauke.

Jedan od glavnih ciljeva ovog skupa bio je uspostavljanje kontakata s mladim istraživačima porijeklom iz Bosne i Hercegovine koji djeluju u STEM oblastima na univerzitetima i istraživačkim institucijama u svijetu.

Skup je prvenstveno bio namijenjen studentima doktorskih studija u STEM oblastima i mladim istraživačima koji su doktorirali u posljednjih pet godina, ali i svim zainteresiranim istraživačima, članovima akademske i naučne zajednice u Bosni i Hercegovini te predstavnicima bh. privrede.

Skup se sastojao iz tri dijela: dva pozivna predavanja koja su održali gospodin Namik Hrle, inostrani član ANUBiH, IBM Fellow, direktor IBM-ovih globalnih razvojnih timova iz područja baza podataka i umjetne inteligencije i direktor IBM-ove najveće razvojne laboratorije u Njemačkoj i Suad Krilašević, doktorand na Tehničkom univerzitetu u Delftu i predsjednik Asocijacije za napredak nauke i tehnologije u Bosni i Hercegovini.

U drugom dijelu skupa predstavljeno je 28 prezentacija istraživanja studenata III ciklusa i mladih istraživača koji su doktorirali u proteklih 5 godina. Naučni odbor skupa dodijelio novčane nagrade za najbolje prezentacije istraživanja.

KLF Collaboration

At the first stage the KLF (K Long Facility) program will focus on two-body and quasi-two-body reactions: elastic $K_L p → KS_p$ and charge-exchange $K_L p → K^+ n$ reactions, then on two-body reactions producing $S = −1$ ($S = −2$) hyperons as $K_L p → π + \Lambda$, $K_L p → \pi+Σ^0$ , and $K_L p → π^0 \Sigma^+ (K_L p → K+Ξ 0 )$, as well as three body $K_L p → K^+ K^+ \Omega^ −$.

A coupled channel PWA of the KLF data can be performed standalone and in conjunction with an analysis of the data from the J-PARC K−p measurements, if available. The best fit will determine the partial wave amplitudes and the resonance pole positions, residues and Breit-Wigner (BW) parameters. These will provide a benchmark for results of forthcoming Lattice QCD calculations and elucidate the structure of the strange hyperons.

PWA Tuzla Group is a part of the KLF Collaboration.

Single-energy partial-wave analysis for pion photoproduction with fixed-t analyticity

Received 15 July 2021

Accepted 20 August 2021

DOI:https://doi.org/10.1103/PhysRevC.104.034605

Abstract

Experimental data for pion photoproduction including differential cross sections and various polarization observables from four reaction channels, $\gamma p \rightarrow \pi^0 p$, $\gamma p \rightarrow \pi^+ n$, $\gamma n \rightarrow \pi^− p$, and $\gamma n \rightarrow \pi^0  n$, from threshold up to W= 2.2 GeV were used in order to perform a single-energy partial-wave analysis with minimal model dependence by imposing constraints from unitarity and fixed-t analyticity in an iterative procedure. Reaction models were only used as a starting point in the very first iteration. We demonstrate that with this procedure partial-wave amplitudes can be obtained which show only a minimal dependence on the initial model assumptions. The analysis was obtained in full isospin, and the Watson theorem is enforced for energies below W= 1.3 GeV but is even fulfilled up to W≈ 1.6 GeV in many partial waves. Electromagnetic multipoles $E_{ℓ\pm}$ and $M _{ℓ\pm}$ are presented and discussed for S, P, D, and F waves.

Single-energy partial wave analysis for π0 photoproduction on the proton with fixed-t analyticity imposed

  • Received 16 August 2019

Abstract 

High-precision data of the $\gamma p \rightarrow \pi^0p$ reaction from its threshold up to W=1.9GeV have been used in order to perform a single-energy partial-wave analysis with minimal model dependence. Continuity in energy was achieved by imposing constraints from fixed-t analyticity in an iterative procedure. Reaction models were only used as starting point in the very first iteration. We demonstrate that, with this procedure, partial-wave amplitudes can be obtained which show only a minimal dependence on the initial model assumptions.
