    Phenomenology from the Lattice PoS(Lattice 2010)018 Christopher Sachrajda∗ School of Physics and Astronomy University of Southampton Southampton SO17 1BJ, UK E-mail: [email protected] In recent years the precision of lattice calculations has improved hugely, and the results are mak- ing a very significant impact in particle physics phenomenology. Indeed there is no alternative general method which can be used in the evaluation of nonperturbative strong interaction effects for a wide variety of physical processes. In this talk I discuss a selection of topics in flavour physics, including mature quantities for which lattice calculations have been performedfor a long time (e.g. the determination of the Vus CKM matrix element and BK), quantities which we are now learning to study (e.g. K ππ decays amplitudes and the spectrum and mixing of η η → − ′ mesons) and important phenomenological quantities for which a large amount of experimental data is available but which we do not yet understand how to approach in lattice simulations (e.g. nonleptonic B-decays). The improvement in precision and the extension of the range of processes which can be studied using lattice QCD has to be continuedvigorously if precision flavour physics is to play a complementary role to large P discovery experiments at the LHC in unravelling the ⊥ next level of fundamental physics.

The proposal is twin track: Firstly to deploy a lower risk but mission critical baseline of new GPU aware algorithms that transform the level of locality by factoring the Fermion determinant to change the balance between interconnect speed and computing throughput. Secondly, to combine this with a higher risk, but high potential reward machine learned change of variables to accelerate the sampling and avoid critical slowing down. Expected Results: The Exascale-aware baseline algorithm is estimated to be a factor of ten faster than current algorithms on the DOE Aurora supercomputer at ANL, by evading communication. The machine learned algorithm field transformation can augment this gain further. These improvements will enable science that aligns with major lab priorities: ● Enable theoretical simulations using chiral fermion discretisations to be performed on substantially finer “grids” than ever before, allowing the inclusion of charm quarks and use of larger momenta.

For K ππ decayswe show that the breakingof isospin symmetry by the twisted bound- → ary conditions implies that the amplitudes cannot be determined in general. We find numerical evidence for the result that the finite volume effects of the boundary conditions are exponentially suppressed for quantities without final state interactions (meson masses and meson-to-vacuum matrix elements) in a simulation with partial twisting on a sea of Nf = 2 non-perturbatively im- arXiv:hep-lat/0509093v1 22 Sep 2005 proved Wilson quarks.

Sect. 3 describes the presentation of our scientific results at international conferences and describes our networking activity. We discuss the economic spin–off of our research activity in Sect. 4. Finally we conclude. 1 Research Achievements In this section we describe the scientific activity of the nodes with emphasis on the relation to the working groups and to milestones defined in Annex I of the FLAVIAnet contract. Node No. 1: Spain-V (Universitat de Valencia` Estudi General [UVEG]) In collaboration with nodes 9 and 11 [19] a detailed comparison between the results of (quenched) 2 Annual Report — Research Activity lattice QCD and the predictions of (quenched) ChPT at NLO has been performed. In particular, two different chiral regimes (p- and ǫ-regimes) have been considered. Volume and quark mass dependence of current correlators has been studied. In the ǫ regime, also the dependence on the topological charge has been investigated. Finally, the leading order LECs F and Σ have been extracted in the two regimes (milestone no.

We discuss the framework for in- cluding radiative corrections in leptonic and semileptonic decays of hadrons, including the treat- ment of infrared divergences. We briefly review isospin breaking in leptonic decays and present the first numerical results for the ratio G(Km2)=G(pm2) in which these corrections have been in- cluded. We also discuss the additional theoretical issues which arise when including electromag- netic corrections to semileptonic decays, such as K`3 decays.

  • Novel Quantum Monte Carlo Approaches for Quantum Liquids
    Novel Quantum Monte Carlo Approaches for Quantum Liquids Brenda M. Rubenstein Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy under the Executive Committee in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2013 c 2013 Brenda M. Rubenstein All Rights Reserved ABSTRACT Novel Quantum Monte Carlo Approaches for Quantum Liquids Brenda M. Rubenstein Quantum Monte Carlo methods are a powerful suite of techniques for solving the quantum many-body problem. By using random numbers to stochastically sample quantum proper- ties, QMC methods are capable of studying low-temperature quantum systems well beyond the reach of conventional deterministic techniques. QMC techniques have likewise been indispensible tools for augmenting our current knowledge of superfluidity and superconduc- tivity. In this thesis, I present two new quantum Monte Carlo techniques, the Monte Carlo Power Method and Bose-Fermi Auxiliary-Field Quantum Monte Carlo, and apply previ- ously developed Path Integral Monte Carlo methods to explore two new phases of quantum hard spheres and hydrogen. I lay the foundation for a subsequent description of my re- search by first reviewing the physics of quantum liquids in Chapter 2 and the mathematics behind Quantum Monte Carlo algorithms in Chapter 3. I then discuss the Monte Carlo Power Method, a stochastic way of computing the first several extremal eigenvalues of a matrix too memory-intensive to be stored and therefore diagonalized. As an illustration of the technique, I demonstrate how it can be used to determine the second eigenvalues of the transition matrices of several popular Monte Carlo algorithms. This information may be used to quantify how rapidly a Monte Carlo algorithm is converging to the equilibrium probability distribution it is sampling.

The Training and TOK activities have been organized, supervised and coordinated among the several nodes by the FLAVIAnet Training Committee composed by M. Davier (Orsay), S. Descotes Genon (Orsay), P. Krizan (Ljubljana), P. Hernandez (Valencia), T. Mannel (Siegen), C. T. Sachrajda (Southampton) and chaired by N. Brambilla (Technical U. Munich). In the following we report the training and TOK achievements for each of the eleven FLAVIAnet nodes in the period 01/10/2006–30/09/2010. For each one of the Early Stage Researchers (ESR) and each one of the Experienced Researchers (ER) of our network a detailed and personalized Career Development Plan has been constructed by the Network Training Committee in collaboration with the node tutors. In establishing the Career Path for our researchers we have considered a global Career Plan covering both short term and long terms objectives, being the long term ones projected over a period of five years, thus including also the time after the conclusion of this network. The network has been fully committed to grant to the young researcher all the relevant skills and tools to allow them to develop into independent and creative researchers, to enlarge and create their own scientific vision, to make possible that they acquire all the relevant scientific, managerial, leadership and communicational capabilities such to open up different perspectives and opportunities for them in the future.
