Long-Lived Particles at the Energy Frontier: The MATHUSLA Physics Case
David Curtin, Marco Drewes, Matthew McCullough +85
We examine the theoretical motivations for long-lived particle (LLP) signals at the LHC in a comprehensive survey of Standard Model (SM) extensions. LLPs are a common prediction of…
Unification and New Particles at the LHC
Nima Arkani-Hamed, Raffaele Tito D'Agnolo, Matthew Low +1
Precision gauge coupling unification is one of the primary quantitative successes of low energy or split supersymmetry. Preserving this success puts severe restrictions on possible…
Nnaturalness
Nima Arkani-Hamed, Timothy Cohen, Raffaele Tito D'Agnolo +3
We present a new solution to the electroweak hierarchy problem. We introduce copies of the Standard Model with varying values of the Higgs mass parameter. This generically yiel…
Stealth Supersymmetry Simplified
JiJi Fan, Rebecca Krall, David Pinner +2
In Stealth Supersymmetry, bounds on superpartners from direct searches can be notably weaker than in standard supersymmetric scenarios, due to suppressed missing energy. We present…
Folded Supersymmetry with a Twist
Timothy Cohen, Nathaniel Craig, Hou Keong Lou +1
Folded supersymmetry (f-SUSY) stabilizes the weak scale against radiative corrections from the top sector via scalar partners whose gauge quantum numbers differ from their Standard…
The Weak Scale from BBN
Lawrence J. Hall, David Pinner, Joshua T. Ruderman
The measured values of the weak scale, , and the first generation masses, , are simultaneously explained in the multiverse, with all these parameters scanning indepen…
A keV String Axion from High Scale Supersymmetry
Brian Henning, John Kehayias, Hitoshi Murayama +2
Various theoretical and experimental considerations motivate models with high scale supersymmetry breaking. While such models may be difficult to test in colliders, we propose look…
Prospects and Blind Spots for Neutralino Dark Matter
Clifford Cheung, Lawrence J. Hall, David Pinner +1
Using a simplified model framework, we assess observational limits and discovery prospects for neutralino dark matter, taken here to be a general admixture of bino, wino, and Higgs…
Yukawa Unification and the Superpartner Mass Scale
Gilly Elor, Lawrence J. Hall, David Pinner +1
Naturalness in supersymmetry (SUSY) is under siege by increasingly stringent LHC constraints, but natural electroweak symmetry breaking still remains the most powerful motivation f…
A Natural SUSY Higgs Near 125 GeV
Lawrence J. Hall, David Pinner, Joshua T. Ruderman
The naturalness of a Higgs boson with a mass near 125 GeV is explored in a variety of weak-scale supersymmetric models. A Higgs mass of this size strongly points towards a non-mini…
Seesaw Spectroscopy at Colliders
Clifford Cheung, Lawrence J. Hall, David Pinner
A low-scale neutrino seesaw may be probed or even reconstructed at colliders provided that supersymmetry is at the weak scale and the LSP is a sterile sneutrino. Because the neutri…
