The Forward Physics Facility (FPF) is a proposal to create cavern with the space and infrastructure support suite of far-forward experiments at Large Hadron Collider during High Luminosity era. Located along beam collision axis shielded from interaction point by least 100 m concrete rock, FPF will house that detect particles outside acceptance existing large LHC observe rare exotic processes in an extremely low-background environment. In this work, we summarize current status plans for FPF,...

We introduce a new approach to the Higgs naturalness problem. The mixes with dilaton of conformal field theory (CFT) sector whose true ground state has large negative vacuum energy. If expectation value is nonzero and below $\mathcal{O}(\mathrm{TeV})$, CFT admits second metastable vacuum, where expansion history Universe conventional. As result, only Hubble patches unnaturally small values mass do not immediately crunch. main experimental prediction this mechanism in 0.1--10 GeV range that...
A bstract We propose a simple modification of the Goldberger-Wise mechanism for stabilizing scale spontaneously broken conformal theories. The source explicit symmetry breaking is relevant operator with small coefficient, as opposed to usual an almost marginal order-one coefficient. In warped 5D picture this stabilization corresponds tadpole bulk scalar on UV brane, which can be technically natural if it only (for example, discrete Z 2 ). This has significant consequences nature phase...
We present a new solution to the Higgs hierarchy problem based on dynamical vacuum selection mechanism in landscape which scans mass. In patches where mass parameter takes natural value, potential only admits minimum with large and negative energy density. This causes cosmological crunch, removing such from landscape. Conversely, is smaller than critical metastable standard history. value determined by instability scale, quartic coupling turns due its running. The ability of this explain...

We propose a new mechanism to produce axion dark matter from inflationary fluctuations. Quantum fluctuations during inflation are strengthened by coupling of the kinetic term inflaton, which we parametrize as an effective curvature $\kappa$ in equation motion. A nonvanishing breaks scale invariance power spectrum, driving quantum phase transition with order parameter. The spectrum is proportional inverse comoving horizon $\kappa$. For positive gets red tilt, leading exponential enhancement...
A bstract We present a holographic calculation of energy correlators in simple model confinement based on warped extra dimension with an IR brane. For small distances we reproduce the constant strongly-coupled conformal field theory, while for large effects dominate and decay exponentially. find exact shockwave solutions to Einstein equations presence brane, hence avoiding need perturbative expansion terms Witten diagrams. While some expected qualitative features quantum chromodynamics (QCD)...
We study the experimental constraints on Georgi-Machacek model from direct searches for new Higgs bosons and measurements of properties discovered 125 GeV boson. apply these by interfacing public codes HiggsBounds 5.2.0 HiggsSignals 2.2.1, which implement a large collection direct-search extra state to calculator GMCALC. also involving doubly-charged Drell-Yan production neutral with decays photon pairs directly into GMCALC; channels are not included in but provide important model,...
We present a novel construction for Higgs-VEV sensitive operator, which can be used as trigger operator in cosmic selection models the electroweak hierarchy problem. Our does not contain any degrees of freedom charged under SM gauge symmetries, leading to reduced tuning resulting models. is based on extension two Higgs doublet model (2HDM) with softly broken approximate global $D_8$ symmetry (the group square). A crunching our extended sector has only percent level corresponding usual little...

The thermal relic with its abundance determined by freeze-out annihilations to dilatons, Goldstone boson symmetry. If dilaton heavier than this an example forbidden DM. explore phenomenology in 5D dual description, corresponding warped extra dimension Standard Model on ultraviolet brane and infrared brane. find compatible theoretical experimental constraints for masses 0...
We explore higher-derivative terms in the low-energy effective action for dilaton, Goldstone boson of spontaneously broken scale invariance. Focusing on simplest holographic realization invariance, Randall-Sundrum (RS) scenario, we identify nonlinear RS dilaton by integrating out Kaluza-Klein graviton modes. The coefficient a particular four-derivative self-interaction can be identified with Weyl $a$-anomaly dual conformal field theory, which use to verify anomaly matching arguments. also...
We look for relations among CKM matrix elements that are not consequences of the Wolfenstein parametrization. In particular, we search products raised to integer powers approximately equal $1$. study running and resolve an apparent discrepancy in literature. To a good approximation only $A$ runs, parameters. Using Standard Model renormalization group at energy scales ranging from electroweak scale Planck scale, find 19 such relations. These could point structure UV, or be numerical...

We calculate energy correlators in a general holographic model of confinement, involving an asymptotically anti-de Sitter (AdS) warped extra dimension. Building on recent computation minimal hard-wall we show that the shockwave method for efficiently computing AdS generalizes to arbitrary geometry. This is possible because exact, linear solutions 5D field equations exist any background. apply our formalism compute two-point correlator two simple models confinement with interesting infrared...
