Dark Matter Candidates from Particle Physics and Methods of Detection
The identity of dark matter is a question of central importance in both astrophysics and particle physics. In the past, the leading particle candidates were cold and collisionless, and typically
Review of Particle Physics: Particle data group
This biennial Review summarizes much of particle physics. Using data from previous editions, plus 2658 new measurements from 644 papers, we list, evaluate, and average measured properties of gauge
Protophobic Fifth-Force Interpretation of the Observed Anomaly in ^{8}Be Nuclear Transitions.
The protophobic X boson may also alleviate the current 3.6σ discrepancy between the predicted and measured values of the muon's anomalous magnetic moment.
Superweakly interacting massive particles.
This work considers the concrete examples of gravitino and graviton cold dark matter in models with supersymmetry and universal extra dimensions, respectively, and shows that super-WIMP dark matter satisfies stringent constraints from big bang nucleosynthesis and the cosmic microwave background.
Precision Measurement of the Boron to Carbon Flux Ratio in Cosmic Rays from 1.9 GV to 2.6 TV with the Alpha Magnetic Spectrometer on the International Space Station.
Knowledge of the rigidity dependence of the boron to carbon flux ratio (B/C) is important in understanding the propagation of cosmic rays. The precise measurement of the B=C ratio from 1.9 GV to
FASER’s physics reach for long-lived particles
FASER,the ForwArd Search ExpeRiment,is a proposed experiment dedicated to searching for light, extremely weakly-interacting particles at the LHC. Such particles may be produced in the LHC's
ForwArd Search ExpeRiment at the LHC
New physics has traditionally been expected in the high-$p_T$ region at high-energy collider experiments. If new particles are light and weakly-coupled, however, this focus may be completely
Particle physics models for the 17 MeV anomaly in beryllium nuclear decays
The $6.8\ensuremath{\sigma}$ anomaly in excited $^{8}\mathrm{Be}$ nuclear decays via internal pair creation is fit well by a new particle interpretation. In a previous analysis, we showed that a 17
Naturalness and the Status of Supersymmetry
For decades, the unnaturalness of the weak scale has been the dominant problem motivating new particle physics, and weak-scale supersymmetry has been the dominant proposed solution. This paradigm is
Kaluza-Klein dark matter.
We propose that cold dark matter is made of Kaluza-Klein particles and explore avenues for its detection. The lightest Kaluza-Klein state is an excellent dark matter candidate if standard model
