Title: Fundamental Physics with Optically Levitated Objects
Abstract: In the past few years, optical cooling and manipulating of macroscopic objects, such as micro-mirrors and cantilevers has developed into an active field of research. In mechanical systems, the oscillator is attached to its suspension, a thermal contact that limits the motion isolation. On the other hand, when these small objects are levitated using the radiation pressure force of lasers, the excellent thermal isolation even at room temperatures helps produce very sensitive force detectors, and eventually quantum transducers for quantum computation purposes. These new techniques may have a variety of applications for fundamental physics such as short distance tests of gravity and gravitational wave detection at high frequencies. In addition, there are several proposals suggesting that optically levitated dielectrics can be cooled to the ground state of the center of mass motion, opening the exciting possibility of creating macroscopic matter-wave interferometers.

Title:The Mu2e Experiment: Searching Deeper for the Meaning of Flavor
Host: Svoboda
Room: 432
Abstract: Since its discovery in 1936, the muon has posed deep challenges to our understanding of fundamental physics. With the longest lifetime of any unstable fundamental particle, the muon also offers unique experimental opportunities to probe for connections in the flavor sector. The Mu2e experiment will search for the direct conversion of muons into electrons, a process sensitive to many forms of New Physics. By using solenoidal transport and other unconventional beam systems, Mu2e will stop an unprecedented 10^18 muons with very little background, allowing a sensitivity to the relative conversion rate of a few 10^-17. With a factor of 10^4 sensitivity improvement over previous experiments, Mu2e will probe New Physics effective mass scales up to 10^4 TeV. Scheduled to start operation in 2019 on Fermilab's new muon campus, Mu2e will provide us with a deeper understanding of flavor.

Title: Counting Degrees of Freedom in d=3 QFTs
Room: 432
Abstract: The ability to rigorously count degree of freedom in a QFT has lead to many fantastic results in recent years. However, in d=3 defining an appropriate way to count has not been constructed. In this talk I will discuss various approaches to this problem, including those undertaken by myself. These include extensions of the work of Komargodski and Schwimmer, F-maximization and Entanglement Entropy.

Title: Are there hidden scalars in the LHC results?
Host: Gunion
Room: 432
Abstract: In the Two Higgs Doublet Model, scalars heavier than the 125 GeV state recently discovered at the LHC are predicted. Those heavier particles - a charged scalar H^+, a pseudoscalar A and a heavier CP-even state H - can decay to to lighter scalar h, and for considerable regions of parameter space, those decays have branching ratios close to unity. Their production cross-sections at the LHC can be quite large as well, and as such there is the possibility that part of the scalars we are currently seeing at the LHC are the result of the decay of the heavier states. In that sense, we may already, unknowingly, be observing extra scalars at the LHC. We will show that this mechanism of chain Higgs production can amount to as much as 20% of the number of scalars produced at the LHC.

Title: Sequestering the Standard Model Vacuum Energy
Host: Ennio Salvioni
Room: 432
Abstract: We propose a very simple reformulation of General Relativity, which completely sequesters from gravity all of the vacuum energy from a matter sector, including all loop corrections and renders all contributions from phase transitions automatically small. The idea is to make the dimensional parameters in the matter sector functionals of the 4-volume element of the universe. For them to be nonzero, the universe should be finite in spacetime. If this matter is the Standard Model of particle physics, our mechanism prevents any of its vacuum energy, classical or quantum, from sourcing the curvature of the universe. The mechanism is consistent with the large hierarchy between the Planck scale, electroweak scale and curvature scale, and early universe cosmology, including inflation. Consequences of our proposal are that the vacuum curvature of an old and large universe is not zero, but very small, that w_DE ~ -1 is a transient, and that the universe will collapse in the future.

Title: Searching for Dark Matter at the LHC
Host: Yuhsin Tsai
Room: 432
Abstract: The next run of the LHC potentially will provide information about new physics connected to dark matter. I will discuss recent work aimed at classifying dark matter collider signals from a bottom-up approach, in particular in the context of monojet and related searches. This has led to strong constraints on certain kinds of interactions, as well as possible new avenues for probing dark matter physics with the LHC. I will focus on a few examples, including production associated with heavy quarks and production associated with a Higgs boson.
