A complete asymptotically safe embedding of the Standard Model

Steven Abel, Esben Molgaard, Francesco Sannino

We present and discuss the "Tetrad Model", a large colour/flavour embedding of the Standard model which has an interacting ultraviolet fixed point. It is shown that its extended-Pa…

Properties of the decay using the approximate -corrections and the principle of maximum conformality

Qing Yu, Xing-Gang Wu, Sheng-Quan Wang +3

The Higgs boson decay channel, , is one of the most important channels for probing the properties of the Higgs boson. In the paper, we reanalyze its decay width by using th…

Developing the MeV potential of DUNE: Detailed considerations of muon-induced spallation and other backgrounds

Guanying Zhu, Shirley Weishi Li, John F. Beacom

The Deep Underground Neutrino Experiment (DUNE) could be revolutionary for MeV neutrino astrophysics, because of its huge detector volume, unique event reconstruction capabilities,…

Understanding the energy resolution of liquid argon neutrino detectors

Alexander Friedland, Shirley Weishi Li

Available estimates for the energy resolution of DUNE vary by as much as a factor of four. To address this controversy, and to connect the resolution to the underlying physical pro…

Why the angular distribution of the top decay lepton is unchanged by anomalous coupling

Rohini M. Godbole, Michael E. Peskin, Saurabh D. Rindani +1

We give a simple physical argument to understand the observation that the angular distribution of the top decay lepton depends only on the polarisation of the top and is independen…

Precision Predictions at NLO for the Higgs Boson Rapidity Distribution at the LHC

Falko Dulat, Bernhard Mistlberger, Andrea Pelloni

We present precise predictions for the Higgs boson rapidity distribution at the LHC in the gluon fusion production mode. Our approach relies on the fully analytic computation of si…

Using QCD Counting rules to Identify the Production of Gluonium

Stanley J. Brodsky, Felipe J. Llanes-Estrada

The empirical identification of bound states of gluons has remained a central goal of hadron spectroscopy. We suggest an experimentally challenging, but model--independent way to a…

Inelastic Dark Matter at the LHC Lifetime Frontier: ATLAS, CMS, LHCb, CODEX-b, FASER, and MATHUSLA

Asher Berlin, Felix Kling

Visible signals from the decays of light long-lived hidden sector particles have been extensively searched for at beam dump, fixed-target, and collider experiments. If such hidden…

Dissection of an SO(5) x U(1) Gauge-Higgs Unification Model

Jongmin Yoon, Michael E. Peskin

We analyze models of electroweak symmetry breaking in warped 5-dimensional space with gauge bosons and fermions in the bulk. The Higgs boson is identified with the 5th component of…

Kinetic Mixing and Portal Matter Phenomenology

Thomas G. Rizzo

Dark photons (DP) are interesting as potential mediators between the dark matter (DM) sector and the fields of the Standard Model (SM). The interaction of the DP, described by a br…

Hadronic Final States in DIS at NNLO QCD with Parton Showers

Stefan Höche, Silvan Kuttimalai, Ye Li

We present a parton-shower matched NNLO QCD calculation for hadronic final state production in Deep Inelastic Scattering. The computation is based on the UNLOPS method and is imple…

Nonperturbative strange-quark sea from lattice QCD, light-front holography, and meson-baryon fluctuation models

Raza Sabbir Sufian, Tianbo Liu, Guy F. de Téramond +5

We demonstrate that a nonzero strangeness contribution to the spacelike electromagnetic form factor of the nucleon is evidence for a strange-antistrange asymmetry in the nucleon's…

DUNE as the Next-Generation Solar Neutrino Experiment

Francesco Capozzi, Shirley Weishi Li, Guanying Zhu +1

We show that the Deep Underground Neutrino Experiment (DUNE), with significant but feasible new efforts, has the potential to deliver world-leading results in solar neutrinos. With…

Freezing-in the Hierarchy Problem

Timothy Cohen, Raffaele Tito D'Agnolo, Matthew Low

Models with a tiny coupling between the dark matter and the Standard Model, , can yield the measured relic abundance through the thermal proce…

New Weak-Scale Physics from SO(10) with High-Scale Supersymmetry

Sebastian A. R. Ellis, Tony Gherghetta, Kunio Kaneta +1

Gauge coupling unification and the stability of the Higgs vacuum are among two of the cherished features of low-energy supersymmetric models. Putting aside questions of naturalness…

Elliptic polylogarithms and two-loop Feynman integrals

Johannes Broedel, Claude Duhr, Falko Dulat +2

We review certain classes of iterated integrals that appear in the computation of Feynman integrals that involve elliptic functions. These functions generalise the well-known class…

A Thermal Neutrino Portal to Sub-MeV Dark Matter

Asher Berlin, Nikita Blinov

Thermal relics lighter than an MeV contribute to the energy density of the universe at the time of nucleosynthesis and recombination. Constraints on extra radiation degrees of free…

Consequences of Fine-Tuning for Fifth Force Searches

Nikita Blinov, Sebastian A. R. Ellis, Anson Hook

Light bosonic fields mediate long range forces between objects. If these fields have self-interactions, i.e., non-quadratic terms in the potential, the experimental constraints on…

Extending the Predictive Power of Perturbative QCD

Bo-Lun Du, Xing-Gang Wu, Jian-Ming Shen +1

The predictive power of perturbative QCD (pQCD) depends on two important issues: (1) how to eliminate the renormalization scheme-and-scale ambiguities at fixed order, and (2) how t…

The Spin Structure of the Nucleon

A. Deur, S. J. Brodsky, G. F. de Teramond

We review the present understanding of the spin structure of protons and neutrons, the fundamental building blocks of nuclei collectively known as nucleons. The field of nucleon sp…
