Abstract

In the light of recent experimental results from IceCube, LHC searches for scalar leptoquark, and the flavor anomalies RK and RK , we analyze two scalar leptoquark models with hypercharge Y ¼ 1=6 and Y ¼ 7=6. We consider the 53 high-energy starting events from IceCube and perform a statistical analysis, taking into account both the Standard Model and leptoquark contribution together. The lighter leptoquark states that are in agreement with IceCube are strongly constrained from LHC di-lepton+dijet search. Heavier leptoquarks in the TeV mass range are in agreement both with IceCube and LHC. We furthermore show that leptoquark, which explains the B-physics anomalies and does not have any coupling with the third generation of quarks and leptons, can be strongly constrained.
