The anatomy of $$K^+\rightarrow \pi ^+\nu {\bar{\nu }}$$ K + → π + ν ν ¯ distributions
Autor: Martin Gorbahn, Ulserik Moldanazarova, Kai Henryk Sieja, Emmanuel Stamou, Mustafa Tabet
Publikováno v: European Physical Journal C: Particles and Fields, Vol 84, Iss 7, Pp 1-15 (2024)
Abstract The excellent experimental prospects to measure the invisible mass spectrum of the $$K^+\rightarrow \pi ^+\nu {\bar{\nu }}$$ K + → π + ν ν ¯ decay opens a new path to test generalised quark–neutrino interactions with flavour changing

Generic one-loop matching conditions for rare meson decays
Autor: Fady Bishara, Joachim Brod, Martin Gorbahn, Ulserik Moldanazarova
Publikováno v: Journal of High Energy Physics, Vol 2021, Iss 7, Pp 1-21 (2021)
Abstract Leptonic and semileptonic meson decays that proceed via flavour-changing neutral currents provide excellent probes of physics of the standard model and beyond. We present explicit results for the Wilson coefficients of the weak effective Lag

The Z penguin in generic extensions of the Standard Model
Autor: Joachim Brod, Martin Gorbahn
Publikováno v: Journal of High Energy Physics, Vol 2019, Iss 9, Pp 1-26 (2019)
Abstract Precision flavour observables play an important role in the interpretation of results at the LHC in terms of models of new physics. We present the result for the one-loop Z penguin in generic extensions of the standard model which exhibit ex

Two-loop amplitudes for Higgs plus jet production involving a modified trilinear Higgs coupling
Autor: Martin Gorbahn, Ulrich Haisch
Publikováno v: Journal of High Energy Physics, Vol 2019, Iss 4, Pp 1-13 (2019)
Abstract We calculate the contributions to the two-loop scattering amplitudes h → gg, h → ggg and h → q q ¯ g $$ h\to q\overline{q}g $$ that arise from a modified trilinear Higgs coupling λ. Analytic expressions are obtained by performing an

Constraints on the trilinear Higgs coupling from vector boson fusion and associated Higgs production at the LHC
Autor: Wojciech Bizoń, Martin Gorbahn, Ulrich Haisch, Giulia Zanderighi
Publikováno v: Journal of High Energy Physics, Vol 2017, Iss 7, Pp 1-25 (2017)
Abstract We examine the constraints on the trilinear Higgs coupling λ that originate from associated (V h) and vector boson fusion (VBF) Higgs production in pp collisions in the context of the Standard Model effective field theory. The 1-loop contri

Rare meson decays are among the most sensitive probes of both heavy and light new physics. Among them, new physics searches using kaons benefit from their small total decay widths and the availability of very large datasets. On the other hand, useful

Standard-Model Prediction of εK with Manifest Quark-Mixing Unitarity
Autor: Martin Gorbahn, Joachim Brod, Emmanuel Stamou
Publikováno v: PHYSICAL REVIEW LETTERS
Physical Review Letters
The parameter εK describes CP violation in the neutral kaon system and is one of the most sensitive probes of new physics. The large uncertainties related to the charm-quark contribution to εK have so far prevented a reliable standard-model predict

Non-Standard neutrino Interactions (NSI) are vector contact interactions involving two neutrinos and two first generation fermions, which can affect neutrino propagation in matter. SU(2) gauge invariance suggests that NSI should be accompanied by mor
