Two-loop mixed QCD-electroweak amplitudes for jet production at the LHC: bosonic corrections

Piotr Bargiela, Fabrizio Caola, Herschel Chawdhry +1

We present a calculation of the bosonic contribution to the two-loop mixed QCD-electroweak scattering amplitudes for -boson production in association with one hard jet at hadron…

Decoding the excess at Belle II: kinematics, operators, and masses

Kåre Fridell, Mitrajyoti Ghosh, Takemichi Okui +1

An excess in the branching fraction for recently measured at Belle II may be a hint of new physics. We perform thorough likelihood analyses for different new physi…

Two-Loop Master Integrals for Leading-Color Amplitudes with a Light-Quark Loop

F. Febres Cordero, G. Figueiredo, M. Kraus +2

We compute the two-loop master integrals for leading-color QCD scattering amplitudes including a closed light-quark loop in production at hadron colliders. Exploiting n…

p-adic reconstruction of rational functions in multi-loop amplitudes

Herschel A. Chawdhry

Numerical reconstruction techniques are widely employed in the calculation of multi-loop scattering amplitudes. In recent years, it has been observed that the rational functions in…

Light Dilaton in Rare Meson Decays and Extraction of its CP Property

Sudhakantha Girmohanta, Yuichiro Nakai, Yoshihiro Shigekami +1

The dilaton is a pseudo-Nambu-Goldstone boson associated with the spontaneous breaking of scale invariance in a nearly conformal theory, and couples to the trace of the stress-…

Extraction of the neutron F2 structure function from inclusive proton and deuteron deep-inelastic scattering data

Shujie Li, Alberto Accardi, Matteo Cerutti +7

The available world deep-inelastic scattering data on proton and deuteron structure functions F2p, F2d, and their ratios, are leveraged to extract the free neutron F2n structure fu…

MeV Sterile Neutrino in light of the Cabibbo-Angle Anomaly

Teppei Kitahara, Kohsaku Tobioka

A modified neutrino sector could imprint a signature on precision measurements of the quark sector because many such measurements rely on the semi-leptonic decays of the charged cu…

Computing Tools for Effective Field Theories

Jason Aebischer, Matteo Fael, Javier Fuentes-Martín +30

In recent years, theoretical and phenomenological studies with effective field theories have become a trending and prolific line of research in the field of high-energy physics. In…

Lepton flavor physics at colliders

Kåre Fridell, Ryuichiro Kitano, Ryoto Takai

We discuss sensitivities to lepton flavor violating (and conserving) interactions at future muon colliders, especially at colliders. Compared with the searches for rare de…

Light quark and antiquark constraints from new electroweak data

Alberto Accardi, Xiaoxian Jing, Joseph Francis Owens +1

We present a new parton distribution function analysis which includes new data for W boson production in proton-proton collisions and lepton pair production in proton-proton and pr…

Probing long-lived axions at the KOTO experiment

Yoav Afik, Babette Döbrich, Jan Jerhot +2

While the main goal of the J-PARC KOTO experiment is to measure the rare decay , the unique setup of KOTO raises the possibility to search for physics beyond t…

Target mass corrections in lepton--nucleus DIS: theory and applications to nuclear PDFs

R. Ruiz, K. F. Muzakka, C. Leger +14

Motivated by the wide range of kinematics covered by current and planned deep-inelastic scattering (DIS) facilities, we revisit the formalism, practical implementation, and numeric…
