SURF: Announcements of Opportunity
Below are Announcements of Opportunity posted by Caltech faculty and JPL technical staff for the SURF program. Each AO indicates whether or not it is open to non-Caltech students. If an AO is NOT open to non-Caltech students, please DO NOT contact the mentor. Announcements of Opportunity are posted as they are received. Please check back regularly for new AO submissions!
Remember: This is just one way that you can go about identifying a suitable project and/or mentor. Click here for more tips on finding a mentor. Announcements for external summer programs are listed here.
*Students applying for JPL projects should complete a SURF@JPL application instead of a "regular" SURF application.
*Students pursuing opportunities at JPL must be U.S. citizens or U.S. permanent residents.

| Background: | There are multiple opportunities available at the intersection of experimental particle physics with CMS at the CERN Large Hadron Collider (LHC), and using artificial intelligence (AI) / machine learning (ML) for improving analysis and computing techniques. These opportunities are available for both SURF and term-time research all year round, for Caltech students only. | ||||||||
| Description: |
Example Projects Project 1: This project aims to boost the search for high energy pairs of Higgs bosons using state-of-the-art deep learning techniques for identifying Higgs decays to tau leptons. Searching for Higgs boson pairs allows us to understand the dynamics of the very early universe, through measurement of the Higgs self-coupling and thereby the shape of the Higgs potential. This is why measuring HIggs pair production (HH) is a flagship physics target of the LHC in the coming decades. This project explores a novel data analysis strategy to do so, looking for highly Lorentz-boosted Higgs bosons decays to two bottom quarks (bb) and two tau leptons (ττ). H→ττ is a very rich and complicated decay, and we aim to hep.explore ML techniques such as graph and transformer networks to improve its identification and reconstruction. Project 2: Simulations are critical in particle physics to understanding what we expect to observe in our experiments. However, traditional methods can be computationally intensive and likely will not be able to scale to the exponentially increasing data volume we expect in the coming decades. In this project, we aim to use generative AI techniques, such as diffusion and flow-matching models that have shown great promise in computer vision, to simulate particle collisions. |
