Precise estimate of charged Wino decay rate
Journal of High Energy Physics, 2023 The Wino is an SU(2) L triplet Majorana fermion and a well-motivated dark matter candidate. The mass difference between the charged and the neutral Winos is small thanks to the SU(2) L symmetry. The small mass difference makes the charged Wino metastable,

Wino potential and Sommerfeld effect at NLO
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2020 We calculate the SU(2)×U(1) electroweak static potential between a fermionic triplet in the broken phase of the Standard Model in the one-loop order (NLO).

Zero-range effective field theory for resonant wino dark matter. Part III. Annihilation effects
Journal of High Energy Physics, 2018 Near a critical value of the wino mass where there is a zero-energy S-wave resonance at the neutral-wino-pair threshold, low-energy winos can be described by a zero-range effective field theory (ZREFT) in which the winos interact nonperturbatively ...

Zero-range effective field theory for resonant wino dark matter. Part II. Coulomb resummation
Journal of High Energy Physics, 2018 Near a critical value of the wino mass where there is a zero-energy S-wave resonance at the neutral-wino-pair threshold, low-energy winos can be described by a zero-range effective field theory (ZREFT) in which the winos interact nonperturbatively ...

Zero-range effective field theory for resonant wino dark matter. Part I. Framework
Journal of High Energy Physics, 2017 The most dramatic “Sommerfeld enhancements” of neutral-wino-pair annihilation occur when the wino mass is near a critical value where there is a zero-energy S-wave resonance at the neutral-wino-pair threshold.

Mass of decaying wino from AMS-02 2014
Physics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2015 We revisit the decaying wino dark matter scenario in the light of the updated positron fraction, electron and positron fluxes in cosmic ray recently reported by the AMS-02 collaboration.

Likelihood analysis of the minimal AMSB model [PDF]
European Physical Journal C: Particles and Fields, 2017 We perform a likelihood analysis of the minimal anomaly-mediated supersymmetry-breaking (mAMSB) model using constraints from cosmology and accelerator experiments. We find that either a wino-like or a Higgsino-like neutralino LSP, $$\tilde{\chi }^0_{1}$$

Determining wino lifetime in supersymmetric model at future 100 TeV pp colliders
Physics Letters B, 2020 We discuss a possibility to measure the lifetime of charged Wino in supersymmetric model at future 100TeV pp colliders, assuming that (neutral) Wino is the lightest superparticle (LSP). In the Wino LSP scenario, the charged Wino has a lifetime of about 0.
