Adding Pseudo-Observables to the Four-Lepton Experimentalist's Toolbox
James S. Gainer, Martín González-Alonso, Admir Greljo +12
The "golden" channel, in which the newly-discovered Higgs boson decays to four leptons by means of intermediate vector bosons, is important for determining the properties of the Hi…
US Cosmic Visions: New Ideas in Dark Matter 2017: Community Report
Marco Battaglieri, Alberto Belloni, Aaron Chou +248
This white paper summarizes the workshop "U.S. Cosmic Visions: New Ideas in Dark Matter" held at University of Maryland on March 23-25, 2017.
Golden Probe of Electroweak Symmetry Breaking
Yi Chen, Joe Lykken, Maria Spiropulu +2
The ratio of the Higgs couplings to and pairs, , is a fundamental parameter in electroweak symmetry breaking as well as a measure of the (approximate) custodial s…
Implications of Gauge Invariance on a Heavy Diphoton Resonance
Ian Low, Joseph Lykken
Assuming a heavy electroweak singlet scalar, which couples to the Standard Model gauge bosons only through loop-induced couplings, SU(2)_L x U(1)_Y gauge invariance imposes interes…
Technical Note for 8D Likelihood Effective Higgs Couplings Extraction Framework in the Golden Channel
Yi Chen, Emanuele DiMarco, Joe Lykken +3
In this technical note we present technical details on various aspects of the framework introduced in arXiv:1401.2077 aimed at extracting effective Higgs couplings in the $h\to 4\e…
Light Dark Matter, Naturalness, and the Radiative Origin of the Electroweak Scale
Wolfgang Altmannshofer, William A. Bardeen, Martin Bauer +2
We study classically scale invariant models in which the Standard Model Higgs mass term is replaced in the Lagrangian by a Higgs portal coupling to a complex scalar field of a dark…
Exploring Theory Space with Monte Carlo Reweighting
James S. Gainer, Joseph Lykken, Konstantin T. Matchev +2
Theories of new physics often involve a large number of unknown parameters which need to be scanned. Additionally, a putative signal in a particular channel may be due to a variety…
Beyond Geolocating: Constraining Higher Dimensional Operators in with Off-Shell Production and More
James S. Gainer, Joseph Lykken, Konstantin T. Matchev +2
We extend the study of Higgs boson couplings in the "golden" channel in two important respects. First, we demonstrate the importance of off-shell Hi…
Testing the Muon g-2 Anomaly at the LHC
Ayres Freitas, Joseph Lykken, Stefan Kell +1
The long-standing difference between the experimental measurement and the standard-model prediction for the muon's anomalous magnetic moment, , may be explained by…
Super-Razor and Searches for Sleptons and Charginos at the LHC
Matthew R. Buckley, Joseph D. Lykken, Christopher Rogan +1
Direct searches for electroweak pair production of new particles at the LHC are a difficult proposition, due to the large background and low signal cross sections. We demonstrate h…
The Matrix Element Method: Past, Present, and Future
James S. Gainer, Joseph Lykken, Konstantin T. Matchev +2
The increasing use of multivariate methods, and in particular the Matrix Element Method (MEM), represents a revolution in experimental particle physics. With continued exponential…
Geolocating the Higgs Boson Candidate at the LHC
James S. Gainer, Joseph Lykken, Konstantin T. Matchev +2
The latest results from the ATLAS and CMS experiments at the CERN Large Hadron Collider (LHC) unequivocally confirm the existence of a resonance, , with mass near 125 GeV which…
Have We Observed the Higgs (Imposter)?
Ian Low, Joseph Lykken, Gabe Shaughnessy
We interpret the new particle at the Large Hadron Collider as a CP-even scalar and investigate its electroweak quantum number. Assuming an unbroken custodial invariance as suggeste…
The pMSSM Interpretation of LHC Results Using Rernormalization Group Invariants
Marcela Carena, Joseph Lykken, Sezen Sekmen +2
The LHC has started to constrain supersymmetry-breaking parameters by setting bounds on possible colored particles at the weak scale. Moreover, constraints from Higgs physics, flav…
Stops and MET: the shape of things to come
Daniele S. M. Alves, Matthew R. Buckley, Patrick J. Fox +2
LHC experiments have placed strong bounds on the production of supersymmetric colored particles (squarks and gluinos), under the assumption that all flavors of squarks are nearly d…
