A bstract Searches for dark photons provide serendipitous discovery potential other types of vector particles. We develop a framework recasting photon searches to obtain constraints on more general theories, which includes data-driven method determining hadronic decay rates. demonstrate our approach by deriving that couples the B-L current, leptophobic B boson directly baryon number and leptons via - γ kinetic mixing, mediates protophobic force. Our can easily be generalized any massive...

It is intended to summarize the main characteristics that these have when applied searches at LHC, provide number useful expressions reference. The list includes both s-channel t-channel scenarios. For s-channel, spin-0 spin-1 mediations are discussed, also realizations where Higgs particle provides portal between visible sectors. guiding principles underpinning proposed...

We will reach this hitherto inaccessible regime physics analysing electron-photon photon-photon interactions in extreme environment provided intense focus. The background its relevance are...
We propose an inclusive search for dark photons A^{'} at the LHCb experiment based on both prompt and displaced dimuon resonances. Because couplings of photon are inherited from via kinetic mixing, A^{'}→μ^{+}μ^{-} rate can be directly inferred off-shell γ^{*}→μ^{+}μ^{-} rate, making this a fully data-driven search. For run 3 LHC, we estimate that will have sensitivity to large regions unexplored dark-photon parameter space, especially in 210-520 MeV 10-40 GeV mass ranges. This leverages...

We derive model-independent constraints arising from the Z and W boson observables on dimension six operators in effective theory beyond Standard Model. In particular, we discuss generic flavor structure for these as well several patterns motivated by simple new physics scenarios.
We present a novel data-driven method for determining the hadronic interaction strengths of axionlike particles (ALPs) with QCD-scale masses. Using our method, it is possible to calculate production and decay rates ALPs, along many largest ALP exclusive final states. To illustrate impact on phenomenology, we consider scenario where ALP-gluon coupling dominant over photons, electroweak bosons, all fermions m_{π}≲m_{a}≲3 GeV. emphasize, however, that can easily be generalized any set couplings...
We show that both flavor-conserving and flavor-violating Yukawa couplings of the Higgs boson to first- second-generation quarks can be probed by measuring rare decays form h→MV, where M denotes a vector meson V indicates either γ, W or Z. calculate branching ratios for these processes in standard model its possible extensions. discuss experimental prospects their observation. The possibility accessing appears unique high-luminosity LHC future hadron colliders, providing further motivation...
We show that new physics models without flavor violating interactions can explain the recent anomalies in $b\ensuremath{\rightarrow}s{\ensuremath{\ell}}^{+}{\ensuremath{\ell}}^{\ensuremath{-}}$ transitions. The arises from a ${Z}^{\ensuremath{'}}$ penguin which automatically predicts $V\ensuremath{-}A$ structure for quark currents effective operators. This framework either be realized renormalizable $U(1{)}^{\ensuremath{'}}$ setup or due to strongly interacting dynamics. dimuon resonance...
We propose a novel approach to probe new fundamental interactions using isotope shift spectroscopy in atomic clock transitions. As concrete toy example we focus on the Higgs boson couplings building blocks of matter: electron and up down quarks. show that attractive force between nuclei their bound electrons, which is poorly constrained, might induce effects are larger than current experimental sensitivities. More generically, discuss how neutrons, mediated via light degrees freedom, may...
We explore the sensitivity of photon-beam experiments to axionlike particles (ALPs) with QCD-scale masses whose dominant coupling standard model is either photons or gluons. introduce a novel data-driven method that eliminates need for knowledge nuclear form factors flux when considering coherent Primakoff production off target, and show data collected by PrimEx experiment in 2004 could improve ALPs 0.03≲m_{a}≲0.3 GeV an order magnitude. Furthermore, we potential running GlueX target its...

A bstract We investigate the phenomenological implications of recent W mass measurement by CDF collaboration, which exhibits tension with standard model (SM) electroweak fit. Performing fit to observables within SM effective field theory, we find that new physics contributes either determination vacuum expectation value, or oblique parameters, can improve agreement data. The best description is obtained from a where flavor universality not required in operators, 2 3 σ indications for several...
A bstract The Electron-Ion Collider (EIC), a forthcoming powerful high-luminosity facility, represents an exciting opportunity to explore new physics. In this article, we study the potential of EIC probe coupling between axion-like particles (ALPs) and photons in coherent scattering. ALPs can be produced via photon fusion decay back two inside detector. prompt-decay search, find that set most stringent bound for m ≲ 20 GeV effective scales Λ 10 5 GeV. displaced-vertex which requires adopting...
We introduce four different types of data-driven analyses with level robustness that constrain the size Higgs-charm Yukawa coupling: (i) recasting vector-boson associated, Vh, search for bottom-pair final state. use this mode to directly and model independently Higgs charm coupling, y_c/y_c^{SM} < 234; (ii) direct measurement total width, 120-140; (iii) h -> J/\psi\gamma, 220; (iv) a global fit signal strengths, 6.2. A comparison t\bar{t}h data allows us show current eliminates possibility...
We discuss the prospects to probe light-quark Yukawa couplings Higgs boson. The coupling charm quark can be probed both via inclusive and exclusive approaches. On frontier, we use our recently proposed method together with published experimental studies for sensitivity of bottom quarks find that high-luminosity LHC sensitive modifications order a few times its standard model (SM) value. also present preliminary study this mode 100 TeV hadronic machine (with similar luminosity) bound further...
If $t\rightarrow hq$ ($q=c,u$) or $h\rightarrow\tau\ell$ ($\ell=\mu,e$) decays are observed, it will be a clear signal of new physics. We investigate whether natural and viable flavor models can saturate the present direct upper bounds without violating indirect constraints from low energy loop processes. carry out our analysis in two theoretical frameworks: minimal violation (MFV) Froggatt-Nielsen symmetry (FN). The simplest either framework predict changing couplings that too small to...
We show that the normalized Higgs production $p_T$ and $y_h$ distributions are sensitive probes of couplings to light quarks. For up and/or down quark Yukawa comparable SM $b$ $\bar u u$ or d d$ fusion could lead appreciable softer distribution than in SM. The rapidity distribution, on other hand, becomes more forward. find that, owing partially a downward fluctuation, one can derive competitive bounds two using ATLAS measurements at 8\,TeV. With 300 fb${}^{-1}$ 13\,TeV LHC establish flavor...
