We show that this change of speed is observable with the current LIGO sensitivity for a class of self-interacting ultralight DM models, where the DM particles could form... More » inSPIRE

20170323 March 23, 2017 Double Scalar Production at LHC and Beyond Ian Lewis, University of Delaware Zhen The simplest extension of the Standard Model is to add a gauge singlet scalar: the singlet extended Standard Model.  Although simple, this model is quite well-motivated and has an interesting phenomenology.  Of particular interest is that this model can provide a mechanism for the strong first order phase transition necessary for electroweak baryogenesis. In this... More » InSPIRE profile
20170330 March 30, 2017 Conformal QED3 and the ε expansion Emmanuel Stamou, University of Chicago Pilar The theory of Quantum Electrodynamics in three dimensions (QED3) has received considerable attention due to its applications in condensed matter physics and due to its similarities with stongly coupled QCD-like theories in four dimensions. QED3 is strongly coupled at energies close to the gauge coupling that in this case is dimensionful. Whereas for a large... More » inSPIRE profile
20170406 April 6, 2017 Effective theories for point sources Cliff Burgess, McMaster/PI Paddy Nature comes to us with many hierarchies of scale, and science progresses because we do not need to understand them all at once. Effective theories exploit this fact to isolate what is important at any scale. This talk summarizes how effective theories work for applications to the ordinary and relativistic quantum mechanics of a particle... More » InSPIRE profile

20170522 May 22, 2017 D* Polarization as a probe to distinguish new physics in B → D*τν Uma Sankar, Indian Institute of Technology Bombay Marcela BaBar, Belle and LHCb have all measured the parameters R(D) and R(D*) to be in excess of the Standard Model predictions.  Freytsis et al (arXiv:1506.08896) have obtained the coupling strengths of various New Physics operators which can explain this excess. In this work (arXiv:1606.03164), we look at the angular observables which can distinguish between these different solutions. We find that... More »

20170711 July 11, 2017 Axion-photon transition (radiation) caused by dielectric interfaces in a magnetic field: QFT approach Ara Ioannisyan, Yerevan Physics Institute, Armenia Axion-photon transition/conversion at dielectric interfaces, immersed in a near-homogeneous magnetic field, is the basis for the dielectric haloscope method to search for axion dark matter. In analogy to transition radiation, this process is possible because the photon wave function is modified by the dielectric layers (“Garibian wave function”) and is no longer an eigenstate of...

20170712 July 12, 2017 Impact of the magnetic field in EoS, the structure and velocities of the Quark Stars Aurora Perez Martinez, Havana, ICIMAF Marcela We analyze the impact of anisotropic EoS, due to the presence of a magnetic field, in the structure equations of  magnetized quark stars. We assume a cylindrical metric and an anisotropic energy momentum tensor for the source. We found that there is a maximum magnetic field that a quark star can sustain, closely related to...

20170720 July 20, 2017 New opportunities for old observables at LHC Marc Riembau, DESY Interpreting LHC data requires a few assumptions, even from an Effective Field Theory approach. I will put a question mark on a few on them and study their effects: considering triple Higgs coupling in single Higgs observables gives a complementarity between single and double Higgs; adding anomalous fermion-vector boson couplings in diboson data ends up...

20170727 July 27, 2017 Toward partial compositeness on the lattice: Lattice results from a candidate SU(4) gauge theory William Jay, Colorado Uni. Ciaran In this seminar, I’ll discuss recent results from lattice simulation of a candidate model of physics beyond the Standard Model. In systems of interest, the Higgs arises as a Goldstone boson of a new strongly coupled sector in the UV, while the top quark obtains its large mass through the mechanism of partial compositeness. This... More » Inspires Profile

In this setup the coupling of the dark matter flavour triplet to SM quark triplets constitutes the only new source of flavour and CP violation.
