Neutrino Effects on Atomic Measurements of the Weinberg Angle

Mitrajyoti Ghosh, Yuval Grossman, Chinhsan Sieng +1

We derive a complete expression for the neutrino-mediated quantum force beyond the four-Fermi approximation within the Standard Model. Using this new result, we study the effect of…

Impact of Higgs-boson measurements on SMEFT fits

J. de Blas, A. Goncalves, V. Miralles +3

We present current bounds on SMEFT operators that are mainly constrained by Higgs-boson observables, under different assumptions for the flavour structure of the UV theory. We inve…

New Bounds on Heavy QCD Axions from Big Bang Nucleosynthesis

Tae Hyun Jung, Takemichi Okui, Kohsaku Tobioka +1

We study Big Bang Nucleosynthesis (BBN) constraints on heavy QCD axions. BBN offers a powerful probe of new physics that modifies the neutron-to-proton ratio during the process, th…

Constraining new physics effective interactions via a global fit of electroweak, Drell-Yan, Higgs, top, and flavour observables

J. de Blas, A. Goncalves, V. Miralles +3

We present results from a global fit of Standard Model parameters and dimension-6 SMEFT Wilson coefficients that includes electroweak, Drell-Yan, Higgs-boson, top-quark, and flavou…

Ambiguities in the Partial-Wave Analysis of the Photoproduction of Pairs of Pseudoscalar Mesons

J. Guo, E. Barriga, K. Scheuer +8

Applying the technique of partial-wave analysis, there are cases where more than one set of underlying complex-valued amplitudes can describe the measured observables. These ambigu…

Review of heat and charge transport in strongly magnetized relativistic plasmas

Igor A. Shovkovy, Ritesh Ghosh

We review field-theoretic studies of charge transport in hot relativistic plasmas under strong magnetic fields and extend the analysis to thermal conductivity. The calculations rel…

Neutrino properties from muonium-antimuonium mixing

Mitrajyoti Ghosh, Kevin Liguori, Takemichi Okui +1

The nature of neutrino mass -- whether neutrinos are Dirac or Majorana particles -- remains one of the central open questions in particle physics. While observation of neutrinoless…

High Energy Vector Boson Scattering in Four-Body Final States to Probe Higgs Cubic, Quartic, and HEFT interactions

Shameran Mahmud, Kohsaku Tobioka

We compute the energy scales of perturbative unitarity violation in various vector boson scattering (VBS) processes and compare them to lower multiplicity processes. The…

Systematic uncertainties from higher-twist corrections in DIS at large x

Matteo Cerutti, Alberto Accardi, Ishara P. Fernando +3

We investigate the systematic uncertainties and potential biases arising from the inclusion of large- corrections to proton and deuteron deep inelastic scattering (DIS) data in…
