Ashutosh V. Kotwal

Ashutosh V. Kotwal is the Fritz London Distinguished Professor of Physics at Duke University, affiliated with the Department of Physics. His research focuses on the physics of fundamental particles and forces at high energies, particularly through precision measurements of fundamental parameters and direct searches for new particles and forces. He leads global efforts to measure the W boson mass, which is sensitive to the properties of the Higgs boson. Kotwal has published five world-leading measurements of the W boson mass, achieving a precision of 0.02% in 2012 and an improved precision of 0.01% in 2022. His work has revealed significant deviations from Standard Model predictions, suggesting new physics beyond current theories. He also contributes to the ATLAS experiment at the LHC, exploring Higgs and top quark compositeness, dark matter, and other phenomena. Kotwal is a Fellow of the American Physical Society and the American Association for the Advancement of Science.

Ashutosh Vijay Kotwal is a particle physicist at Duke University, specializing in experimental particle physics. His research focuses on the study of fundamental particles and their interactions, particularly through the ATLAS detector at the Large Hadron Collider (LHC). His work includes the observation of new particles, such as the Higgs boson, and the analysis of various detector performance metrics. He has contributed to the measurement of jet energy scales, missing transverse momentum reconstruction, and the performance of trigger systems in high-energy collisions. His research also involves the study of electrons, muons, and hadron production cross sections in proton-proton collisions.
