beyond the standard model

Avital Dery, Mitrajyoti Ghosh

We analyze the New Physics sensitivity of a recently proposed method to measure the CP-violating decay rate using interference. We pre…

Radiative Quark Jet Function with an External Gluon

Ze Long Liu, Matthias Neubert, Marvin Schnubel +1

Factorization theorems in soft-collinear effective theory at subleading order in power counting involve ``radiative jet functions'', defined in terms of matrix elements of collinea…

Flavor probes of axion-like particles

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 (SM). We investigate the phenomenology of an ALP with fl…

The Forward Physics Facility: Sites, Experiments, and Physics Potential

Luis A. Anchordoqui, Akitaka Ariga, Tomoko Ariga +78

The Forward Physics Facility (FPF) is a proposal to create a cavern with the space and infrastructure to support a suite of far-forward experiments at the Large Hadron Collider dur…

Resummation of Super-Leading Logarithms

Thomas Becher, Matthias Neubert, Ding Yu Shao

Jet cross sections at high-energy colliders exhibit intricate patterns of logarithmically enhanced higher-order corrections. In particular, so-called non-global logarithms emerge f…

Z-portal Continuum Dark Matter

Csaba Csáki, Sungwoo Hong, Gowri Kurup +3

We examine the possibility that dark matter (DM) consists of a gapped continuum, rather than ordinary particles. A Weakly-Interacting Continuum (WIC) model, coupled to the Standard…

Continuum Dark Matter

Csaba Csáki, Sungwoo Hong, Gowri Kurup +3

We initiate the study of dark matter models based on a gapped continuum. Dark matter consists of a mixture of states with a continuous mass distribution, which evolves as the unive…

as a clean probe of short-distance physics

Avital Dery, Mitrajyoti Ghosh, Yuval Grossman +1

The decay is often considered to be uninformative of fundamental theory parameters since the decay is polluted by long-distance hadronic effects. We demonstrate that,…

Constructing on-shell operator basis for all masses and spins

Zi-Yu Dong, Teng Ma, Jing Shu

We first propose a general method to construct the complete set of on-shell operator bases involving massive particles with any spins. To incorporate the non-abelian little groups…

Reading the footprints of the B-meson flavor anomalies

Claudia Cornella, Darius A. Faroughy, Javier Fuentes-Martin +2

Motivated by the recent LHCb announcement of a violation of lepton-flavor universality in the ratio , we present an updated, comprehen…

Consistent treatment of axions in the weak chiral Lagrangian

Martin Bauer, Matthias Neubert, Sophie Renner +2

We present a consistent implementation of weak decays involving an axion or axion-like particle in the context of an effective chiral Lagrangian. We argue that previous treatments…

Axi-Higgs Cosmology

Leo WH Fung, Lingfeng Li, Tao Liu +3

If the electroweak Higgs vacuum expectation value in early universe is higher than its present value GeV, the Li puzzle in BBN and the CMB/CDM tens…

Probing the Rule in Three Body Charm Decays

Avital Dery, Yuval Grossman, Stefan Schacht +1

CP violation in charm decay was observed in the decays of a meson to two pseudoscalars. When interpreted within the SM, the results imply that…
