Precise estimate of charged Wino decay rate [PDF]
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,

Zero-range effective field theory for resonant wino dark matter. Part III. Annihilation effects [PDF]
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 [PDF]
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 ...

R-parity violating decays of Wino chargino and wino neutralino LSPs and NLSPs at the LHC [PDF]
Journal of High Energy Physics, 2019 The R-parity violating decays of both Wino chargino and Wino neutralino LSPs are analyzed within the context of the B − L MSSM “heterotic standard model”.

Closing in on the Wino LSP via trilepton searches at the LHC [PDF]
Journal of High Energy Physics, 2018 The neutralino dark matter (DM) predicted by the Minimal Supersymmetric Standard Model (MSSM) has been probed in several search modes at the Large Hadron Collider (LHC), one of the leading ones among which is the trilepton plus missing transverse ...

How light a higgsino or a wino dark matter can become in a compressed scenario of MSSM [PDF]
Journal of High Energy Physics, 2017 Higgsinos and Wino have strong motivations for being Dark Matter (DM) candidates in supersymmetry, but their annihilation cross sections are quite large.

Sommerfeld-corrected relic abundance of wino dark matter with NLO electroweak potentials [PDF]
Journal of High Energy Physics, 2021 Extending previous work, we calculate the electroweak potentials for all co-annihilation channels of wino dark matter at the one-loop order and obtain the wino relic abundance including the Sommerfeld effect at the next-to-leading order (NLO).

Wino potential and Sommerfeld effect at NLO [PDF]
Physics Letters B, 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).

Wino-Higgsino dark matter in MSSM from the g − 2 anomaly [PDF]
Physics Letters B, 2021 In this letter, we show that the wino-Higgsino dark matter (DM) is detectable in near future DM direct detection experiments for almost all consistent parameter space in the spontaneously broken supergravity (SUGRA) if the muon g−2 anomaly is explained ...

Discovery reach for wino and higgsino dark matter with a disappearing track signature at a 100 TeV pp collider [PDF]
European Physical Journal C: Particles and Fields, 2019 Within the theory of supersymmetry, the lightest neutralino is a dark matter candidate and is often assumed to be the lightest supersymmetric particle (LSP) as well.
