Newton polytopes of fireworks Grothendieck polynomials Open
We show that the support of the Grothendieck polynomial $\mathfrak G_w$ of any fireworks permutation is as large as possible: a monomial appears in $\mathfrak G_w$ if and only if it divides $\mathbf x^{\mathrm{wt}(\overline{D(w)})}$ and is…

Nipple Sensation and Nipple-Areolar Complex Outcomes After Oncoplastic Breast Surgery. Open
Nipple-areolar outcomes following OBS and adjuvant radiation are favorable in terms of patient sensation and appearance particularly when compared with the contralateral breast undergoing symmetry reduction surgery. These findings can enha…

Recent Progress and Next Steps for the MATHUSLA LLP Detector Open
We report on recent progress and next steps in the design of the proposed MATHUSLA Long Lived Particle (LLP) detector for the HL-LHC as part of the Snowmass 2021 process. Our understanding of backgrounds has greatly improved, aided by deta…

An Update to the Letter of Intent for MATHUSLA: Search for Long-Lived Particles at the HL-LHC Open
We report on recent progress in the design of the proposed MATHUSLA Long Lived Particle (LLP) detector for the HL-LHC, updating the information in the original Letter of Intent (LoI), see CDS:LHCC-I-031, arXiv:1811.00927. A suitable site h…

MATHUSLA: A Detector Proposal to Explore the Lifetime Frontier at the HL-LHC Open
The observation of long-lived particles at the LHC would reveal physics beyond the Standard Model, could account for the many open issues in our understanding of our universe, and conceivably point to a more complete theory of the fundamen…

A Letter of Intent for MATHUSLA: a dedicated displaced vertex detector above ATLAS or CMS Open
In this Letter of Intent (LOI) we propose the construction of MATHUSLA (MAssive Timing Hodoscope for Ultra-Stable neutraL pArticles), a dedicated large-volume displaced vertex detector for the HL-LHC on the surface above ATLAS or CMS. Such…

New detectors to explore the lifetime frontier Open
Long-lived particles (LLPs) are a common feature in many beyond the Standard\nModel theories, including supersymmetry, and are generically produced in exotic\nHiggs decays. Unfortunately, no existing or proposed search strategy will be\nab…

The Higgs Portal and Cosmology Open
Higgs portal interactions provide a simple mechanism for addressing two open problems in cosmology: dark matter and the baryon asymmetry. In the latter instance, Higgs portal interactions may contain the ingredients for a strong first orde…
