On 4 January 1957 Lee mentioned the great news to the physicists who had gathered for the regular Chinese lunch that took place at Columbia every Friday. That parity violation may be real triggered the imagination of many experimental physicists. One of those was Leon Lederman, who that night at around 8 p.m. called Richard Garwin at his home with an idea for an alternative experiment to demonstrate parity violation. Lederman had realized that the muons produced at Columbia University’s cyclotron might already be polarized and hence also suitable for proving parity violation – Lee and Yang had already suggested trying muon experiments. Garwin, an experienced experimental particle physicist, met Lederman at the cyclotron that very night. Their experiment, for which they used the apparatus built for another project by Lederman’s graduate student, Marcel Weinrich, not only worked but did so very convincingly. Within four days they had compelling results and even had a manuscript ready. However, Lee dissuaded them from submitting, saying that this would not be fair to the NBS team, which had by then been working hard on its experiment for months.
1957年1月4日，李政道向聚集在每個星期五在哥倫比亞舉行的中式午餐的物理學家們提了個好消息。宇稱不守恒可能是個事實，引發了許多實驗物理學家的連想。萊昂·萊德曼（Leon Lederman）就是其中之一，他當天晚上8點左右，給在家的理查德·加溫（Richard Garwin）打了個電話，他想出一個替代實驗來證明宇稱不守恒的想法。萊德曼已經意識到，哥倫比亞大學回旋加速器產生的極化介子，因此也適合證明宇稱不守恒，雖然李和楊已經建議嚐試進行介子實驗。那天晚上，經驗豐富的實驗粒子物理學家加溫（Garwin）在回旋加速器上遇見了萊德曼（Lederman）。他們的實驗使用了萊德曼（Lederman）研究生Marcel Weinrich為另一個項目建造的儀器，不僅有效，而且非常令人信服。在四天內，他們取得了令人矚目的成果，甚至準備好了手稿。但是，李政道勸說他們不要提交，說這對NBS團隊不公平，當時NBS團隊已經努力進行了幾個月的實驗。
後來，兩組同時發表了論文，見PhysRev.105.1413.pdf 和 PhysRev.105.1415.pdf
