| 11:00 - 12:00 Wednesday Weekly Seminar-google meet IPM-x, the first IPM and xFitter joint collaboration School PARTICLES AND ACCELERATORS Abstract: We present the first open-source analysis of fragmentation functions (FFs) of charged pions (entitledIPM-xFitter) performed at next-to-leading order (NLO) and next-to-next-to-leadingorder (NNLO) accuracy in perturbative QCD using the xFitter framework. This study incorporates a comprehensive and up-to-date set of pion production data from single-inclusive annihilation (SIA) processes, together with the most recent measurements of inclusive cross-sections of single pion by the BELLE collaboration. The determination of pion FFs along with their theoretical uncertainties is performed in the Zero-Mass Variable-Flavor Number Scheme (ZM-V ... 13:30 - 15:00 Weekly Seminar (Online) ü?CDM in the light of H0 tension and Planck internal inconsistencies https://www.skyroom.online/ch/soa/weekly-seminar School ASTRONOMY The observed discrepancy of the Hubble parameter measurements in the local universe with the CMB data may indicate a new physics. The CMB lensing is a crucial observation that relates the early universe perturbations to the matter’s late time distribution. In this talk, I review cosmic tensions and then explain the predictions of the ü?CDM model as a solution for H0 tension and CMB lensing and also low-ell/high-ell power spectrum internal inconsistency. ... 14:00 - 15:00 Weekly Webinar Suppression (reviving) superconducting transition temperature via charge density wave (nonadiabatic effects) in 2D systems with strong electron-phonon coupling: InSe and blue phosphorene School NANO SCIENCES In this work, the completed investigation of a possible superconducting phase in monolayer indium selenide and blue phosphorene is determined using first-principles calculations for both the hole and electron doping systems. Monolayer InSe: the hole-doped dependence of the Fermi surface is exclusively fundamental for monolayer InSe. It leads to the extensive modification of the Fermi surface from six separated pockets to two pockets by increasing the hole densities. For low hole doping levels of the system, below the Lifshitz transition point, superconductive critical temperatures T c ~55-75 K are obtained within anisotropic Eliashberg theory ... |
