Two bifurcation sets arising from the beta transformation with a hole at $0$Apr 15 2019Given $\beta\in(1,2],$ the $\beta$-transformation $T_\beta: x\mapsto \beta x\pmod 1$ on the circle $[0, 1)$ with a hole $[0, t)$ was investigated by Kalle et al.~(2019). They described the set-valued bifurcation set \[ \mathcal E_\beta:=\{t\in[0, 1): ... More

Strong Lensing of Gamma Ray Bursts as a Probe of Compact Dark MatterSep 25 2018Sep 28 2018Compact dark matter has been efficiently constrained in the M <~ 10 M_sun mass range by null searches for microlensing of stars in nearby galaxies. Here we propose to probe the mass range M >~ 10 M_sun by seeking echoes in gamma-ray-burst light curves ... More

Kinematic Discrimination of tW and tt Productions Using Initial State RadiationMar 12 2015Nov 14 2015Production of a single top quark provides excellent opportunity for understanding top quark physics and Cabibbo-Kobayashi-Maskawa structure of the quark sector in the Standard Model. Although an associated production with a b-quark has already been observed ... More
