Observation of the decay.

Using proton-proton collision data corresponding to an integrated luminosity of collected by the CMS experiment at , the decay is observed for the first time, with a statistical significance exceeding 5 standard deviations. The relative branching fraction, with respect to the decay, is measured to be , where the first uncertainty is statistical, the second is systematic, and the third is related to the uncertainties in and .

Outcomes of pediatric pilonidal disease treatment: excision with off-midline flap reconstruction versus endoscopic pilonidal sinus treatment.

Purpose: Pilonidal disease (PD) is marked by chronic inflammation and frequent recurrence which can decrease quality of life. However, debate remains regarding the optimal treatment for PD in the pediatric population. This study compares two recommended treatment approaches-excision with off-midline flap reconstruction (OMF: Bascom cleft lift flap, modified Limberg flap) and minimally invasive endoscopic pilonidal sinus treatment (EPSiT).

Exploring Health Care Access Among Lesbian, Gay, Bisexual, and Transgender Populations in Orange County, California: A Pilot Cross-sectional Study.

There are approximately 90 000 lesbian, gay, bisexual, and transgender (LGBT) individuals in Orange County, California. LGBT individuals have significant health disparities, particularly if they are from racial or ethnic minority groups and/or have a disability. There are structural and access barriers in the health care system that increase these health disparities.

Measurement of the top quark mass using a profile likelihood approach with the lepton + jets final states in proton-proton collisions at .

The mass of the top quark is measured in 36.3 of LHC proton-proton collision data collected with the CMS detector at . The measurement uses a sample of top quark pair candidate events containing one isolated electron or muon and at least four jets in the final state.
