Probing Isospin-Violating Dark Matter
Jason Kumar
We discuss experimental probes of isospin-violating dark matter (IVDM), including direct and indirect detection strategies. We point out the important role which IVDM plays in unde…
A model of superluminal neutrinos
D. Marfatia, H. Päs, S. Pakvasa +1
Motivated by the tentative observation of superluminal neutrinos by the OPERA experiment, we present a model of active-sterile neutrino oscillations in which sterile neutrinos are…
LHC discovery potential for supersymmetry with \sqrt{s}=7 TeV and 5-30 fb^{-1}
Howard Baer, Vernon Barger, Andre Lessa +1
We extend our earlier results delineating the supersymmetry (SUSY) reach of the CERN Large Hadron Collider operating at a centre-of-mass energy \sqrt{s}=7 TeV to integrated luminos…
Isospin-Violating Dark Matter in the Sun
Yu Gao, Jason Kumar, Danny Marfatia
We consider the prospects for studying spin-independent isospin-violating dark matter-nucleon interactions with neutrinos from dark matter annihilation in the Sun, with a focus on…
Large Jet Multiplicities and New Physics at the LHC
Joseph Bramante, Jason Kumar, Brooks Thomas
A broad class of scenarios for new physics involving additional strongly-interacting fields generically predicts signatures at hadron colliders which consist solely of large number…
Nonstandard Higgs Decays and Dark Matter in the E6SSM
J. P. Hall, S. F. King, R. Nevzorov +2
We study the decays of the lightest Higgs boson within the exceptional supersymmetric (SUSY) standard model (E6SSM). The E6SSM predicts three families of Higgs-like doublets plus t…
Higher Representations and Multi-Jet Resonances at the LHC
Jason Kumar, Arvind Rajaraman, Brooks Thomas
The CMS collaboration has recently conducted a search for trijet resonances in multi-jet events at the LHC. Motivated in part by this analysis, we examine the phenomenology of exot…
B's with Direct Decays: Tevatron and LHC Discovery Prospects in the b\bar{b}+MET Channel
Johan Alwall, Jonathan L. Feng, Jason Kumar +1
We explore the discovery prospects for B'\bar{B}' pair production followed by direct decays B'->bX, where B' is a new quark and X is a long-lived neutral particle. We develop optim…
Dynamical Dark Matter: II. An Explicit Model
Keith R. Dienes, Brooks Thomas
In a recent paper (arXiv:1106.4546), we introduced "dynamical dark matter," a new framework for dark-matter physics, and outlined its underlying theoretical principles and phenomen…
Dynamical Dark Matter: I. Theoretical Overview
Keith R. Dienes, Brooks Thomas
In this paper, we propose a new framework for dark-matter physics. Rather than focus on one or more stable dark-matter particles, we instead consider a multi-component framework in…
Collider Searches for Fermiophobic Gauge Bosons
Joseph Bramante, R. S. Hundi, Jason Kumar +2
We explore the phenomenology of an extra U(1) gauge boson which primarily couples to standard model gauge bosons. We classify all possible parity-odd couplings up to dimension 6 op…
Simplified Models for LHC New Physics Searches
Daniele Alves, Nima Arkani-Hamed, Sanjay Arora +92
This document proposes a collection of simplified models relevant to the design of new-physics searches at the LHC and the characterization of their results. Both ATLAS and CMS hav…
Determination of Weak Amplitudes using Bose Symmetry and Dalitz Plots
Rahul Sinha, N. G. Deshpande, Sandip Pakvasa +1
We present a new method using Dalitz plot and Bose symmetry of pions that allows the complete determination of the magnitudes and phases of weak decay amplitudes. We apply the meth…
LHC Signatures of the Constrained Exceptional Supersymmetric Standard Model
P. Athron, S. F. King, D. J. Miller +2
We discuss two striking Large Hadron Collider (LHC) signatures of the constrained version of the exceptional supersymmetric standard model (cE6SSM), based on a universal high energ…
Detection Prospects for Majorana Fermion WIMPless Dark Matter
Keita Fukushima, Jason Kumar, Pearl Sandick
We consider both velocity-dependent and velocity-independent contributions to spin-dependent (SD) and spin-independent (SI) nuclear scattering (including one-loop corrections) of W…
Dark Matter Detection With Electron Neutrinos in Liquid Scintillation Detectors
Jason Kumar, John G. Learned, Michinari Sakai +1
We consider the prospects for liquid scintillation experiments (with a focus on KamLAND) to detect the flux of electron neutrinos arising from dark matter annihilation in the core…
Dark Energy density in models with Split Supersymmetry and degenerate vacua
C. Froggatt, R. Nevzorov, H. B. Nielsen
In N=1 supergravity supersymmetric (SUSY) and non-supersymmetric Minkowski vacua originating in the hidden sector can be degenerate. In the supersymmetric phase in flat Minkowski s…
Determining the squark mass at the LHC
Vernon Barger, Yu Gao, Andre Lessa +1
We propose a new way to determine the squark mass based on the shape of di-jet invariant mass distribution of supersymmetry (SUSY) di-jet events at the Large Hadron Collider (LHC).…
Isospin-Violating Dark Matter
Jonathan L. Feng, Jason Kumar, Danny Marfatia +1
Searches for dark matter scattering off nuclei are typically compared assuming that the dark matter's spin-independent couplings are identical for protons and neutrons. This assump…
Relating B_s Mixing and B_s -> mu+mu- with New Physics
Eugene Golowich, JoAnne Hewett, Sandip Pakvasa +2
We perform a study of the Standard Model (SM) fit to the mixing quantities , and in order to bound contributions of New Physics to mixing. We th…
