11:00 - 12:00 Wednesday Weekly Seminar - Hybrid Format Exploring SMEFT Couplings Using the Forward-Backward Asymmetry in Neutral Current Drell-Yan Production at the LHC School PARTICLES AND ACCELERATORS Abstract: Neutral current Drell-Yan (DY) lepton-pair production is considered in the framework of the Standard Model Effective Field Theory (SMEFT). Using the open-source fit platform xFitter, we investigate the impact of high-statistics measurements of the neutral current DY (NCDY) forward-backward asymmetry AFB near the weak boson mass scale in the present and forthcoming stages of the Large Hadron Collider (LHC). Besides recovering earlier results on the AFB sensitivity to parton distribution functions, we analyze the precision determination of Z-boson couplings to left-handed and right-handed u-quarks and d-quarks, and expl ... 14:00 - 16:00 Mathematical Logic Weekly Seminar Theory of Fuzzy Time Computation (TC+CON(TC^*)ͰP≠NP) School MATHEMATICS There are different types of approaches to solve P vs NP, some of them are logical approaches. The lecturer's PhD thesis [11] is based on one of these logical approaches 2002 [2], [6]. Till 2011, he and some other logicians made an unsuccessful aƩempt to shed light on this problem in this way. In 2010‐2011, he started to introduce another logical approach based on paradoxes, more specifically ?Unexpected Hanging Paradox?. The goal is to use paradoxes similar to applying paradoxes (Liar Paradoxes) in the Godel?s Incompleteness Theorem [14], [15], [16]. In [5], [16] (2017), he showed by defining a new version of this ... 15:30 - 17:00 Geometry and Topology Weekly Seminar Counting Minimal tori in Riemannian Manifolds School MATHEMATICS The problem of counting closed geodesics in Riemannian Manifolds of con- stant negative curvature has been of interest for many years. A method for counting geodesics in manifolds with arbitrary curvature is introduced by Eftekhary. Minimal surfaces in a Riemannian manifold are higher dimensional gener- alizations of closed geodesics. A natural question is how to count these types of submanifolds. We introduce a function which counts minimal tori in a Riemannian manifold (M, g) with dim M > 4. Moreover, we show that this count function is invariant under perturbations of the metric.
