WebHá 1 dia · Energetic long-lived particles in the CMS muon chambers. Andrea Mitridate, Michele Papucci, Christina Wang, Cristián Peña, Si Xie. We present a recast in different benchmark models of the recent CMS search that uses the endcap muon detector system to identify displaced showers produced by decays of long-lived particles (LLPs). Web3 de jan. de 2024 · No significant excess over the Standard Model expectation is observed. Limits at 95% confidence level on the lifetime of the long-lived particle are presented in …
Web9 de dez. de 2024 · The induction of long-lasting, high-titer antibody responses is critical to the efficacy of many vaccines. The ability to produce durable antibody responses is governed by the generation of the terminally differentiated antibody-secreting B cells known as long-lived plasma cells (LLPCs). Once induced, LLPCs likely persist for decades, …
