Exotic, LFV and LNV Decays at the B Factories

I review the latest results on exotic, lepton flavor violating (LFV) and lepton number violating (LNV) decays of the B, D mesons and the tau leptons, obtained at the two B-factory experiments, Belle and BaBar. Where appropriate, results from other experiments are also described.Comment: 8 pages, 5 figures, 2 tables, Proceedings of CKM2010, the 6th International Workshop on the CKM Unitarity Triangle, University of Warwick, UK, 6-10 September 201

Recent CP violation results from Belle

We summarize recent results on an array of CP violation measurements performed by the Belle experiment using the data collected near the Y(4S) and Y(5S) resonances at the KEKB asymmetric-energy e+e- collider.Comment: 8 pages, 5 postscript figures, contributed to the Proceedings of the Rencontres de Moriond EW 2012, La Thuile, Aosta valley, Ital

Looking for Exotica at the B Factories

Current experiments at the B factories, designed to perform precision measurements of matter-antimatter asymmetry in the B meson system, have a much broader physics reach especially in the sector of quarkonium spectroscopy. Here we present a minireview on the new charmonium-like states observed at the B factories including the X(3872) and Y(4260).Comment: 12 pages, 8 postscript figures, contributed to the Proceedings of the 17th DAE-BRNS High Energy Physics Symposium, IIT, Kharagpur, Indi

Charmless Hadronic B Decays at BABAR

We report recent measurements of branching fractions and charge asymmetries of charmless hadronic B decays using the data collected with the BABAR detector at the PEP-II asymmetric energy e+e- collider.Comment: 7 pages, 4 postscript figures, 3 tables, contributed to the Proceedings of XII International Conference on Hadron Spectroscopy (HADRON07), Frascati, Ital

Charm at Belle II - Status and Prospects

High-precision flavor physics measurements play a complementary role to the direct searches for new physics by CMS and ATLAS experiments at LHC. Such measurements will be performed with the Belle II detector at the upgraded KEKB accelerator (SuperKEKB) in Japan. The physics potential with emphasis on the charm sector, current status and future prospects of the Belle II experiment are presented in these proceedings.Comment: 8 pages, 3 postscript figures, to appear in the proceedings of the 6th International Workshop on Charm Physics (CHARM 2013

New Hadron Spectroscopy with BABAR

We review hadron spectroscopy at BABAR with emphasis on recent results from the studies of the X(3872) state, inclusive charmonia on recoil, double charmonium production, and the broad structure observed at around 4.26 GeV/c^2. These results are preliminary, unless otherwise specified.Comment: 6 pages, 6 postscript figures, contributed to the Proceedings of Frontier Science 200

Measurement of the UT angle phi_2

We give a status report on measurements of the angle phi_2 (alpha) of the CKM unitarity triangle (UT) and the so-called Kpi puzzle. Results presented are mostly from the two B-factory experiments, Belle and BaBar.Comment: 10 pages, 7 figures, 2 tables, Proceedings of the Ninth International Conference on Flavor Physics and CP Violation (FPCP 2011), Maale Hachamisha, Israel, May 23-27, 201

Recent results on hot topics from Belle

We report a sample of recent and topical physics results based on the data recorded with the Belle detector at the KEK B-factory in Japan.Comment: 11 pages, contributed to the Proceedings of the Fifth Workshop on Theory, Phenomenology and Experiments in Flavor Physics (Capri 2014), Anacapri, Capri Island, Ital

Low-Complexity Scheduling Policies for Achieving Throughput and Asymptotic Delay Optimality in Multi-Channel Wireless Networks

In this paper, we study the scheduling problem for downlink transmission in a multi-channel (e.g., OFDM-based) wireless network. We focus on a single cell, with the aim of developing a unifying framework for designing low-complexity scheduling policies that can provide optimal performance in terms of both throughput and delay. We develop new easy-to-verify sufficient conditions for rate-function delay optimality (in the many-channel many-user asymptotic regime) and throughput optimality (in general non-asymptotic setting), respectively. The sufficient conditions allow us to prove rate-function delay optimality for a class of Oldest Packets First (OPF) policies and throughput optimality for a large class of Maximum Weight in the Fluid limit (MWF) policies, respectively. By exploiting the special features of our carefully chosen sufficient conditions and intelligently combining policies from the classes of OPF and MWF policies, we design hybrid policies that are both rate-function delay-optimal and throughput-optimal with a complexity of $O(n^{2.5} \log n)$, where $n$ is the number of channels or users. Our sufficient condition is also used to show that a previously proposed policy called Delay Weighted Matching (DWM) is rate-function delay-optimal. However, DWM incurs a high complexity of $O(n^5)$. Thus, our approach yields significantly lower complexity than the only previously designed delay and throughput optimal scheduling policy. We also conduct numerical experiments to validate our theoretical results.Comment: Accepted for publication by the IEEE/ACM Transactions on Networking. arXiv admin note: text overlap with arXiv:1212.163
