Summary
A mechanism for the decay K 0 L → 2γ is proposed. The closed-loop graph involves two W1 bosons and the W0 which was recently conjectured to exist by Lee. The calculated rate involves a cut-offΛ and the masses of the bosonsm 1 andm 0. The experimental average for the branching ratio is used to obtain the relationm 0 > 0.30Λ, wherem 0 is the mass of the spin-zero W0 boson.
Riassunto
Si propone un meccanismo per il decadimento K 0 L → 2γ. Il grafico ad ansa chiusa coinvolge due bosoni W1 e il W0 di cui Lee ha recentemente congetturato l’esistenza. Il rapporto calcolato coinvolge un taglioΛ e le masse dei bosonim 1 em 0. Si usa la media sperimentale del rapporto di suddivisione per ottenere la relazionem 0 > 0.30Λ, in cuim 0 è la massa del bosone W0.
Реэюме
Предлагается механиэм для распада K 0 L →2γ. График, содержаший эамкнутую петлю, включает два W1 боэона и W0, которые, как было недавно предположено Ли, сушествуют. Вычисленная интенсивность распада включает обреэание Л и массы боэоновm 1 иm 0. Экспериментальное среднее для отнощения ветвей распада испольэуется для полученияm 0 > 0.30 Λ, гдеm 0 масса W0 боэона.
