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…
Polarization options in inclusive DIS off tensor polarized deuteron
Wim Cosyn, Brandon Roldan Tomei, Alan Sosa +1
In the near future, the Jefferson Lab experiment will provide the second measurement of tensor polarized asymmetries in inclusive DIS on the deuteron. In this asymmetry, 4 in…
Neutrino force at all length scales
Mitrajyoti Ghosh, Yuval Grossman, Chinhsan Sieng +1
The Standard Model predicts a long-range force mediated by a pair of neutrinos, known as ``the neutrino force". It scales as , where is the Fermi constant. However…
General mass variable flavor number scheme for boson production in association with a heavy quark at hadron colliders
Marco Guzzi, Pavel Nadolsky, Laura Reina +2
We present a methodology to streamline implementation of massive-quark radiative contributions in calculations with a variable number of active partons in proton-proton collisions.…
Energy-scaling behavior of intrinsic transverse momentum parameters in Drell-Yan simulation
CMS Collaboration
An analysis is presented based on models of the intrinsic transverse momentum (intrinsic ) of partons in nucleons by studying the dilepton transverse momentum in Drel…

Matteo Cadeddu, Nicola Cargioli, Jens Erler +4
We study the impact of nuclear structure uncertainties on a measurement of the weak charge of at the future MESA facility in Mainz. Information from a large varie…
The neutrino force in neutrino backgrounds: Spin dependence and parity-violating effects
Mitrajyoti Ghosh, Yuval Grossman, Walter Tangarife +2
The neutrino force results from the exchange of a pair of neutrinos. A neutrino background can significantly influence this force. In this work, we present a comprehensive calculat…
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…

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-…
