The Low-Energy Effective Theory of Axions and ALPs
Martin Bauer, Matthias Neubert, Sophie Renner +2
Axions and axion-like particles (ALPs) are well-motivated low-energy relics of high-energy extensions of the Standard Model, which interact with the known particles through higher-…
Effective Field Theory for Heavy Vector Resonances Coupled to the Standard Model
Mathias Heiles, Matthias König, Matthias Neubert
We construct an effective field theory describing the decays of a heavy vector resonance into Standard Model particles. The effective theory is built using an extension of Soft…
A warped scalar portal to fermionic dark matter
Adrian Carmona, Javier Castellano Ruiz, Matthias Neubert
We argue that extensions of the SM with a warped extra dimension, together with a new -odd scalar singlet, provide a natural explanation not only for the hierarchy pr…
Dark Matter as a Solution to Muonic Puzzles
Maxim Perelstein, Yik Chuen San
We propose a simple model in which dark matter particle exchanges mediate a new quantum force between muons and nucleons, resolving the proton charge radius puzzle. At the same tim…
Improved Neural Network Monte Carlo Simulation
I-Kai Chen, Matthew D. Klimek, Maxim Perelstein
The algorithm for Monte Carlo simulation of parton-level events based on an Artificial Neural Network (ANN) proposed in arXiv:1810.11509 is used to perform a simulation of $H\to 4\…
Factorization at Subleading Power and Endpoint Divergences in Decay: II. Renormalization and Scale Evolution
Ze Long Liu, Bianka Mecaj, Matthias Neubert +1
Building on the recent derivation of a bare factorization theorem for the -quark induced contribution to the decay amplitude based on soft-collinear effective theory, w…
Factorization at Subleading Power, Sudakov Resummation and Endpoint Divergences in Soft-Collinear Effective Theory
Ze Long Liu, Bianka Mecaj, Matthias Neubert +1
Starting from the first renormalized factorization theorem for a process described at subleading power in soft-collinear effective theory, we discuss the resummation of Sudakov log…
Crunching Dilaton, Hidden Naturalness
Csaba Csaki, Raffaele Tito D'Agnolo, Michael Geller +1
We introduce a new approach to the Higgs naturalness problem, where the value of the Higgs mass is tied to cosmic stability and the possibility of a large observable Universe. The…
CKM Substructure
Yuval Grossman, Joshua T. Ruderman
The CKM matrix is not generic. The Wolfenstein parametrization encodes structure by having one small parameter, . We pose the question: is there substructure in the…
Relations between Decay Modes in Scalar Models
Stefan Schacht, Amarjit Soni
As a consequence of the Ward identity for hadronic matrix elements, we find relations between the differential decay rates of semileptonic decay modes with the underlying quark-lev…
Challenges in Semileptonic B Decays
P. Gambino, A. S. Kronfeld, M. Rotondo +22
Two of the elements of the Cabibbo-Kobayashi-Maskawa quark mixing matrix, and , are extracted from semileptonic B decays. The results of the B factories, analy…
Evolution of the -Meson Light-Cone Distribution Amplitude in Laplace Space
Anne Mareike Galda, Matthias Neubert
The -meson light-cone distribution amplitude is a central quantity governing non-perturbative hadronic dynamics in exclusive decays. We show that the information needed to d…
Renormalization and Scale Evolution of the Soft-Quark Soft Function
Ze Long Liu, Bianka Mecaj, Matthias Neubert +2
Soft functions defined in terms of matrix elements of soft fields dressed by Wilson lines are central components of factorization theorems for cross sections and decay rates in col…
Updated constraints on the Georgi-Machacek model from LHC Run 2
Ameen Ismail, Heather E. Logan, Yongcheng Wu
We study the experimental constraints on the Georgi-Machacek model from direct searches for the new Higgs bosons and measurements of the properties of the discovered 125 GeV Higgs…
A Natural Composite Higgs via Universal Boundary Conditions
Simone Blasi, Csaba Csaki, Florian Goertz
We present a novel realization of a composite Higgs, which can naturally produce top partners above the current LHC bounds without increasing the tuning above 10%. The essential in…
Parameterization and applications of the low- nucleon vector form factors
Kaushik Borah, Richard J. Hill, Gabriel Lee +1
We present the proton and neutron vector form factors in a convenient parametric form that is optimized for momentum transfers few GeV. The form factors are determin…
A benchmark for LHC searches for low-mass custodial fiveplet scalars in the Georgi-Machacek model
Ameen Ismail, Ben Keeshan, Heather E. Logan +1
The Georgi-Machacek (GM) model is used to motivate and interpret LHC searches for doubly charged scalars decaying to vector bosons pairs. The doubly charged scalars are part of a d…
Two-Loop Radiative Jet Function for Exclusive -Meson and Higgs Decays
Ze Long Liu, Matthias Neubert
The rare radiative -meson decay and the radiative Higgs-boson decay mediated by light-quark loops both receive large logarithmic corrections in QCD…
SU(3) Analysis for Beauty Baryon Decays
Avital Dery, Mitrajyoti Ghosh, Yuval Grossman +1
We perform a general SU(3) analysis of decays of members of the beauty baryon antitriplet to a member of the light baryon octet and a singlet. Under…
