Hadronic tau decays at higher orders in QCD
Gauhar Abbas, Vartika Singh
We investigate higher-order perturbative corrections to hadronic decays by applying nonlinear sequence-transformation techniques to the QCD correction . In particula…
Dark-technicolour at colliders
Gauhar Abbas, Vartika Singh, Neelam Singh
We demonstrate that QCD-like gauge dynamics can be consistently embedded within the Dark Technicolor paradigm by invoking the extended Most Attractive Channel hypothesis, thereby r…
A new determination of higher-order QCD corrections to hadronic decays
Gauhar Abbas, Vartika Singh
We employ \textit{Levin-type sequence transformations} to accelerate the convergence of the perturbative fixed-order expansion of the QCD correction in terms of the stro…
Stability of Polling Systems for a Large Class of Markovian Switching Policies
Konstantin Avrachenkov, Kousik Das, Veeraruna Kavitha +1
We consider a polling system with two queues, where a single server is attending the queues in a cyclic order and requires non-zero switching times to switch between the queues. Ou…
Optimal Utility Design with Arbitrary Information Networks
Vartika Singh, Will Wesley, Philip N. Brown
We consider multi-agent systems with general information networks where an agent may only observe a subset of other agents. A system designer assigns local utility functions to the…
