Dark Matter in Light of LUX

Patrick J. Fox, Gabriel Jung, Peter Sorensen +1

The landscape of dark matter direct detection has been profoundly altered by the slew of recent experiments. While some have claimed signals consistent with dark matter, others hav…

Identifying dark matter interactions in monojet searches

Prateek Agrawal, Vikram Rentala

We study the discrimination of quark-initiated jets from gluon-initiated jets in monojet searches for dark matter using the technique of averaged jet energy profiles. We demonstrat…

The CMSSM and NUHM1 after LHC Run 1

O. Buchmueller, R. Cavanaugh, A. De Roeck +12

We analyze the impact of data from the full Run 1 of the LHC at 7 and 8 TeV on the CMSSM with mu > 0 and < 0 and the NUHM1 with mu > 0, incorporating the constraints imposed by oth…

Non-universal gaugino masses and semi-natural supersymmetry in view of the Higgs boson discovery

Stephen P. Martin

I consider models with non-universal gaugino masses at the gauge coupling unification scale, taking into account the Higgs boson discovery. Viable regions of parameter space are ma…

Bounding the Higgs width at the LHC: complementary results from

John M. Campbell, R. Keith Ellis, Ciaran Williams

We investigate the potential of the process to provide bounds on the Higgs width. Recent studies using off-shell events have shown that Run 1 LH…

Probing CP Violation in with Converted Photons

Fady Bishara, Yuval Grossman, Roni Harnik +3

We study Higgs diphoton decays, in which both photons undergo nuclear conversion to electron- positron pairs. The kinematic distribution of the two electron-positron pairs may be u…

W' signatures with odd Higgs particles

Bogdan A. Dobrescu, Andrea D. Peterson

We point out that W' bosons may decay predominantly into Higgs particles associated with their broken gauge symmetry. We demonstrate this in a renormalizable model where the W' and…

Determination of from a lattice-QCD calculation of the semileptonic form factor with physical quark masses

A. Bazavov, C. Bernard, C. Bouchard +21

We calculate the kaon semileptonic form factor from lattice QCD, working, for the first time, at the physical light-quark masses. We use gauge configurations generated by…

Exploring the dark side of the top Yukawa

Sonia El Hedri, Patrick J. Fox, Jay G. Wacker

We investigate simple extensions of the Standard Model that could lead to the negative values of the top Yukawa coupling still allowed by the ATLAS Higgs results. Integrating out t…

Baryon Number Violation

K. S. Babu, E. Kearns, U. Al-Binni +93

This report, prepared for the Community Planning Study - Snowmass 2013 - summarizes the theoretical motivations and the experimental efforts to search for baryon number violation,…

Bounding the Higgs width at the LHC using full analytic results for gg -> 2e 2μ

John M. Campbell, R. Keith Ellis, Ciaran Williams

We revisit the hadronic production of the four-lepton final state, e^- e^+ μ^- μ^+, through the fusion of initial state gluons. This process is mediated by loops of quarks and we p…

Three-loop Standard Model effective potential at leading order in strong and top Yukawa couplings

Stephen P. Martin

I find the three-loop contribution to the effective potential for the Standard Model Higgs field, in the approximation that the strong and top Yukawa couplings are large compared t…

Higgs mass from compositeness at a multi-TeV scale

Hsin-Chia Cheng, Bogdan A. Dobrescu, Jiayin Gu

Within composite Higgs models based on the top seesaw mechanism, we show that the Higgs field can arise as the pseudo Nambu-Goldstone boson of the broken U(3)_L chiral symmetry ass…

Determination of the axial nucleon form factor from the MiniBooNE data

A. V. Butkevich, D. Perevalov

Both neutrino and antineutrino charged-current quasi-elastic scattering on a carbon target are studied to investigate the nuclear effect on the determination of the axial form fact…

Dark Sectors and New, Light, Weakly-Coupled Particles

R. Essig, J. A. Jaros, W. Wester +86

Dark sectors, consisting of new, light, weakly-coupled particles that do not interact with the known strong, weak, or electromagnetic forces, are a particularly compelling possibil…

Dark Matter in the Coming Decade: Complementary Paths to Discovery and Beyond

Sebastian Arrenberg, Howard Baer, Vernon Barger +29

In this Report we discuss the four complementary searches for the identity of dark matter: direct detection experiments that look for dark matter interacting in the lab, indirect d…

Buckets of Higgs and Tops

Matthew R. Buckley, Tilman Plehn, Torben Schell +1

We show that associated production of a Higgs with a top pair can be observed in purely hadronic decays. Reconstructing the top quarks in the form of jet buckets allows us to contr…

Neutrinos: Theory and Phenomenology

Stephen J Parke

The theory and phenomenology of neutrinos will be addressed, especially that relating to the observation of neutrino flavor transformations. The current status and implications for…

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…

Impersonating the Standard Model Higgs Boson: Alignment without Decoupling

Marcela Carena, Ian Low, Nausheen R. Shah +1

In models with an extended Higgs sector there exists an alignment limit, in which the lightest CP-even Higgs boson mimics the Standard Model Higgs. The alignment limit is commonly…

Constraining RS Models by Future Flavor and Collider Measurements: A Snowmass Whitepaper

Kaustubh Agashe, Martin Bauer, Florian Goertz +4

Randall-Sundrum models are models of quark flavor, because they explain the hierarchies in the quark masses and mixings in terms of order one localization parameters of extra dimen…

Yukawa Corrections to Higgs Production in Top Partner Models

Sally Dawson, Elisabetta Furlan

Higgs production from gluon fusion is sensitive to the properties of heavy colored fermions and to the Yukawa couplings, (Y_F M_F)/v, of these particles to the Higgs boson. We comp…

Extracting Effective Higgs Couplings in the Golden Channel

Yi Chen, Roberto Vega-Morales

Kinematic distributions in Higgs decays to four charged leptons, the so called `golden channel, are a powerful probe of the tensor structure of its couplings to neutral electroweak…

Stringent Constraints On The Dark Matter Annihilation Cross Section From Subhalo Searches With The Fermi Gamma-Ray Space Telescope

Asher Berlin, Dan Hooper

The dark matter halo of the Milky Way is predicted to contain a very large number of smaller subhalos. As a result of the dark matter annihilations taking place within such objects…
