A precision relation between Γ(K → μ + μ − )(t) and B K L → μ + μ − / B K L → γγ $$ \mathcal{B}\left({K}_L\to {\mu}^{+}{\mu}^{-}\right)/\mathcal{B}\left({K}_L\to \gamma \gamma \right) $$

open access: yesJournal of High Energy Physics, 2023
We find that the phase appearing in the unitarity relation between B K L → μ + μ − $$ \mathcal{B}\left({K}_L\to {\mu}^{+}{\mu}^{-}\right) $$ and B K L → γγ $$ \mathcal{B}\left({K}_L\to \gamma \gamma \right) $$ is equal to the phase shift in the ...

Kaon differential flow in relativistic heavy-ion collisions [PDF]

open access: yes, 1999
Using a relativistic transport model, we study the azimuthal momentum asymmetry of kaons with fixed transverse momentum, i.e., the differential flow, in heavy-ion collisions at beam momentum of 6 GeV/c per nucleon, available from the Alternating Gradient

Kaonic systems

open access: yesEPJ Web of Conferences, 2012
I make a short review of the situation of the kaonic systems, with novel information supporting the two Λ(1405) states from the K-d → nπΣ reaction. A review is made of the K¯$ar K$NN system with recent calculations converging to smaller bindings and ...

EPJ Featured Talk: First direct measurement of radial flow in heavy-ion collisions with ALICE [PDF]

open access: yesEPJ Web of Conferences
This work presents measurements of the transverse-momentum-dependent observable v0(pT) as a novel probe of radial expansion dynamics in Pb-Pb collisions at √sNN = 5.02 TeV with the ALICE detector. Results are reported for inclusive charged hadrons, pions,

Recent results on Kaon Physics at KLOE-2 [PDF]

open access: yesEPJ Web of Conferences, 2019
KLOE-2 extends the physics program of the forerunner KLOE experiment, especially in the field of discrete symmetries tests with neutral kaons. KLOE and KLOE-2 have collected together the largest sample of electron-positron collisions at an energy equal ...

Investigating the E2 Nuclear Resonance Effects in Kaonic Atoms: The KAMEO Proposal [PDF]

open access: yesEPJ Web of Conferences, 2023
The E2 nuclear resonance effect in kaonic atoms occurs when the energy of atomic de-excitation closely matches the energy of nuclear excitation, leading to the attenuation of some X-ray lines in the resonant isotope target.

Pion–kaon femtoscopy and the lifetime of the hadronic phase in Pb−Pb collisions at sNN=2.76 TeV

open access: yesPhysics Letters B, 2021
In this paper, the first femtoscopic analysis of pion–kaon correlations at the LHC is reported. The analysis was performed on the Pb–Pb collision data at sNN=2.76 TeV recorded with the ALICE detector.

Role of strangeness to the neutron star mass and cooling

open access: yesEPJ Web of Conferences, 2018
Neutron star provides unique environments for the investigation of the physics of extreme dense matter beyond normal nuclear saturation density. In such high density environments, hadrons with strange quarks are expected to play very important role in ...
