SUMMARY:Speaker: Frank Tackmann-Title: "Theory uncertainties and correlations in perturbative predictions  "
DESCRIPTION:Research Progress Meeting \n \nDate: June 15\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Frank Tackmann \nTitle: Theory uncertainties and correlations in perturbative predictions\n \nAbstract: Theoretical predictions that are used in interpreting experimental\nmeasurements require reliable uncertainties and correlations.\nHowever\, the prevalent method to estimate uncertainties in perturbative\npredictions in high-energy physics\, based on varying unphysical scales\, lacks\nboth reliability and the ability to correctly treat correlations.\nThis is a severe limitation in precision studies where theory uncertainties\nare of comparable size to experimental ones.\nI will highlight a couple of such examples\, including determining\nHiggs couplings to bottom and charm from the Higgs pT spectrum\, a recent\ndetermination of the strong coupling from the Drell-Yan pT spectrum by ATLAS\,\nand the measurement of the W-boson mass at hadron colliders.\nI will give a conceptual overview of theory uncertainties and our current\nestimation methods at a non-technical level accessible to non-experts.\nFinally\, I will discuss the development of a new concept of theory nuisance\nparameters\, which promises to overcome (most of) the limitations of scale\nvariations.\n \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09 \nMeeting ID: 988 5432 2464\nPasscode: 142239
