The second part of the The winter conference season is in full swing! 2022 marks the return of full auditoriums and coffee-break chats following UTFSM’s winter break, as one of the most prestiguos universities in Valparaiso welcomes participants to participate presencially or online in the next round of conferences about the ATLAS experiment results regarding LHC Run 2 dataset. These will be the first large-scale, particle physics conferences in Chile to be held in person in the COVID era – reuniting experimentalists and theorists after almost two years of virtual meetings. The conference will begin on Wednesday 22 July, with talks given both in Chile as in Switzerland. ATLAS Collaboration members will be in attendance throughout, presenting a feast of physics results based on the full LHC Run 2 dataset (recorded 2015–2018). As researchers cast their lines into the pool of Run 2 data, they are using ever-more creative bait to lure out rare phenomena. Throughout the conferences, ATLAS scientists will share what they’ve pulled to the surface, including first-of-a-kind observations of Standard Model processes and the most recent insights in the search for new physics. Key results will be explored in physics briefings, with many more presented in conference talks. Explore all of the latest ATLAS results in the links below, which will be updated continuously throughout the course of the year.
Following last week’s excellent presentation made by armenian Phd candidate Estevahan Molinian we will continue with our weekly High Energy Physics talks, this time professor Andrey Borquiev will be giving the a talk titled: T H E ω H A D R O N I Z AT I O N S T U D I E S I N T H E N U C L E A R M E D I U M W I T H T H E C L A S S P E C T R O M E T E R A complete picture of the strong interaction must include hadronization, the dynamical process of a free quark forming a color-neutral hadron. To study the hadronization of the vector meson ω(782), we perform semiinclusive deep-inelastic scattering measurements on deuterium, carbon, iron, and lead using data collected with the CLAS detector at Jefferson Lab employing a 5.014 GeV electron beam. To examine nuclear dependence on the hadron formation, we present ω multiplicities of the solid targets relative to those on deuterium as one-dimensional functions of the virtualphoton energy ν, the photon virtuality Q2, the fractional hadron energy zh, and the square of the hadron transverse momentum p2T. This analysis corresponds to the world’s first hadronization studies of the ω meson and hints at a promising future for upcoming CLAS12 and EIC experiments, where more detailed investigations could be achieved.
