### High Energy Theory Seminar: (g-2)_\mu from lattice QCD and experiments: 4.2 sigma?

##### Zoltán Fodor (Wuppertal University, Pennsylvania State University, Inst. for Theoretical Physics ELTE Eötvös, and Jülich Supercomputing Centre)

Twenty years ago, in an experiment at Brookhaven National Laboratory, physicists detected what seemed to be a discrepancy between measurements of the muon’s magnetic moment and theoretical calculations of…

### Astronomy Seminar: "The Peril and Promise of Three-Dimensional Planets"

##### Emily Rauscher (University of Michigan)

Much to the consternation of spherical cows everywhere, planets are three-dimensional objects. As we try to measure properties of their atmospheres, it may be inappropriate to pretend…

### Mathematical Biology seminar: "Inductive Bias of Neural Networks"

##### Cengiz Pehlevan (Harvard University)

: Predicting a previously unseen example from training examples is unsolvable without additional assumptions about the nature of the task at hand. A learner’s performance depends…

### High Energy Theory Seminar: Cohomology/K-theory of Lie groups and matter representations

##### Mboyo Esole (Northeastern University)

It was recently observed that the matter representations in F-theory compactifications overwhelmingly correspond to characteristic representations of Dynkin embedding index one. I will explain how this…

### Physics and Astronomy Colloquium: "Uncovering New Transport Regimes and Light-Induced Phases in Quantum Materials "

##### Margaret Murnane (University of Colorado – Boulder)

High harmonic generation (HHG) is a unique quantum light source with fundamentally new capabilities, by up-converting femtosecond lasers to very short wavelengths. This produces fully spatially and…

### Mathematical Biology seminar: "Cancer cells and their epithelial neighbors"

##### Katrina Podsypanina (Institut des Hautes Études Scientifiques [IHES])

I am a cancer researcher working on a framework for a new mathematical model of metastasis…

### Thesis Defense: “Characterizing the Outer Solar System with the Dark Energy Survey"

##### Pedro Henrique Bernardinelli (University of Pennsylvania)

### High Energy Theory Seminar: The KLT double-copy bootstrap

##### Henriette Elvang (University of Michigan)

The KLT (Kawai, Lewellen, Tye) formula famously maps a product of open string tree amplitudes to closed string tree amplitudes via a kinematic "KLT kernel" that depends on Mandelstam variables and alpha…

### High Energy Experiment Seminar: Evidence of the four-top-quark production at the LHC

##### Nedaa Alexandra Asbah (Harvard)

Abstract: A summary of the latest results on the evidence of the four-top-quark production using proton-proton collision data at a centre of-mass…

### Astronomy Seminar: How to Find an Earth

##### Megan Bedell (Flatiron)

The detection of an Earth twin (an Earth-mass planet orbiting a Sun-like star within the habitable zone) has recently become feasible for the first time thanks to advances in observational…
