Complete Vector-like Fourth Family with : A Global Analysis

Junichiro Kawamura, Stuart Raby, Andreas Trautner

In this paper we present an in-depth analysis of a recently proposed Standard Model extension with a complete fourth generation of quarks and leptons, which are vector-like with re…

A low-scale flavon model with a symmetry

Tetsutaro Higaki, Junichiro Kawamura

We propose a model that explains the fermion mass hierarchy by the Froggatt-Nielsen mechanism with a discrete symmetry. As a concrete model, we study a supersymmetric model…

Dark Matter meets Quantum Gravity

Manuel Reichert, Juri Smirnov

We search for an extension of the Standard Model that contains a viable dark matter candidate and that can be embedded into a fundamental, asymptotically safe, quantum field theory…

Helicity-dependent generalization of the JIMWLK evolution

Florian Cougoulic, Yuri V. Kovchegov

We generalize the JIMWLK evolution equation to include the small- evolution of helicity distributions. To derive helicity JIMWLK, we use the method devised by A.H. Mueller for t…

W-boson and trident production in TeV--PeV neutrino observatories

Bei Zhou, John F. Beacom

Detecting TeV--PeV cosmic neutrinos provides crucial tests of neutrino physics and astrophysics. The statistics of IceCube and the larger proposed IceCube-Gen2 demand calculations…

Neutrino-nucleus cross sections for W-boson and trident production

Bei Zhou, John F. Beacom

The physics of neutrino-nucleus cross sections is a critical probe of the Standard Model and beyond. A precise understanding is also needed to accurately deduce astrophysical neutr…

Production of and a Photon in Annihilation

Eric Braaten, Li-Ping He, Kevin Ingles

If the is a weakly bound charm-meson molecule, it can be produced in annihilation by the creation of from a virtual photon followed by the…

Branching Fractions of the

Eric Braaten, Li-Ping He, Kevin Ingles

The recoil momentum spectrum from the decay has recently been measured by the BaBar collaboration. The spectrum has a peak with invariant mass near…

Complete Vector-like Fourth Family and new for Muon Anomalies

Junichiro Kawamura, Stuart Raby, Andreas Trautner

We consider the Standard Model (SM) with the addition of a gauge symmetry and a complete fourth family of quarks and leptons which are vector-like with respe…

(Not as) Big as a Barn: Upper Bounds on Dark Matter-Nucleus Cross Sections

Matthew C. Digman, Christopher V. Cappiello, John F. Beacom +2

Critical probes of dark matter come from tests of its elastic scattering with nuclei. The results are typically assumed to be model-independent, meaning that the form of the potent…

Thermal Loop Effects on Large-Scale Curvature Perturbation in the Higgs Inflation

Po-Wen Chang, Cheng-Wei Chiang, Kin-Wang Ng

It is known that the Higgs potential in the Standard Model can drive a successful inflation as long as the Higgs field couples non-minimally to gravity. It is then inevitable to ta…

Strong New Limits on Light Dark Matter from Neutrino Experiments

Christopher V. Cappiello, John F. Beacom

The non-detection of GeV-scale WIMPs has led to increased interest in more general candidates, including sub-GeV dark matter. Direct detection experiments, despite their high sensi…

Eric Braaten, Li-Ping He, Kevin Ingles

If the is a weakly bound charm-meson molecule, it can be produced in annihilation by the creation of from a virtual photon followed by the…

TeV-Scale Thermal WIMPs: Unitarity and its Consequences

Juri Smirnov, John F. Beacom

We re-examine unitarity bounds on the annihilation cross section of thermal-WIMP dark matter. For high-mass pointlike dark matter, it is generic to form WIMP bound states, which, t…

Orbital Angular Momentum at Small

Yuri V. Kovchegov

We determine the small Bjorken asymptotics of the quark and gluon orbital angular momentum (OAM) distributions in the proton in the double-logarithmic approximation (DLA), whic…
