This is my last tweet here.
Now that the bit is up and the joke is over, I should finally reveal who I was. My name is Radha (@rmastand), a particle physicist at Berkeley. I enjoy hard-sphere scattering both in and out of the lab!
Was fun! Follow me on blue sky.

Using simulation-based inference, we show that combining information from kinematic observables with cut-and-count analyses can help to place much tighter constraints on SMEFT Wilson coefficients.
We use di-higgs production as an example, but the method is much more general -- try it out yourself with the public code!

New on the arxiv! We try out a few techniques for anomaly detection for a *non*resonant signal (dark QCD jets) -- background extrapolation seems like a promising way forwards!

Very excited to join this group of fellows! Thanks to @templeton_fdn, I'll be spending a few months in Heidelberg. Hoping to visit as many people on this side of the pond as I can!

Sorry for silence recently, busy hosting #ML4Jets in Hamburg.
Thanks for all the seriously excellent developments on AI applied to particle physics (& beyond)
Not going to summarize the 133 (!) contributions here, but you can check out the slides:

On arXiv today: The Interplay of Machine Learning-based Resonant Anomaly Detection Methods
How do sensitive regions of different #anomaly detectors correlate? A bit wo/ signal, a lot with signal
Can we gain by combining them? Yes - esp. for low signal

We also used this test to find parity violation 👉👈 in simualtions of wacky Lorentz-violating physics doi.org/10.1007/JHEP08(2022)…

ALT In this funny model, differential cross-sections vary with angle ϕ around our p--p collision axis and the parity flip (x 🡢 -x, blue 🡢 orange). We tuned the 'PV-mSME' model to maximize this effect.
I published a method that tests proposed symmetries in data: doi.org/10.1088/1748-0221/17…
