When trying to measure mass() one must distinguish between measurements performed on large and small scales. If the photon acquires mass by the Higgs mechanism, the large-scale behavior of the photon might be effectively Maxwellian. If, on the other hand, one postulates the Proca regime for all scales, the very existence of the galactic field implies mass() < E-26 eV, as correctly calculated by YAMAGUCHI 1959 and CHIBISOV 1976.

TU 2006 continues the work of LUO 2003, with extended LAKES 1998 method, reporting the improved limit mu^2()A = 0.7+-1.7E-13 T/m if A = 0.2 muG out to 4E22 m. Reported result mu = 0.9+-1.5E-52 g reduces to the frequentist mass limit 1.2E-19 eV (FELDMAN 1998). While the results of the torsion balance method give a value for the local limit on mu^2()A, the deduced limit on the photon mass mu is open to question. See the discussions in TU 2005 and GOLDHABER 2003.

FULLEKRUG 2004 adopted KROLL 1971A method with newer and better Schumann resonance data. Result questionable because assumed frequency shift with photon mass is assumed to be linear. It is quadratic according to theorem by GOLDHABER 1971B, KROLL 1971, and PARK 1971.

LUO 2003 extends LAKES 1998 technique to set a limit on mu^2()A, where mu**-1 is the Compton wavelength lambdabar(C) of the massive photon and A is the ambient vector potential. The important departure is that the apparatus rotates, removing sensitivity to the direction of A. They take A = 10**12 Tm, due to ``cluster level fields.'' But see comment of GOLDHABER 2003 and reply by LUO 2003B.

LAKES 1998 reports limits on torque on a toroid Cavendish balance, obtaining a limit on mu**2A <2E-9 Tm/m**2 via the Maxwell-Proca equations, where mu**-1 is the characteristic length associated with the photon mass and A is the ambient vector potential in the Lorentz gauge. Assuming A ~~1E12 Tm due to cluster fields he obtains mu**-1 >2E10 m, corresponding to mu< 1E-17 eV. A more conservative limit, using A ~~(1 muG)x(600 pc) based on the galactic field, is mu**-1 > 1E9 m or mu < 2E-16 eV.

RAFFELT 1994 notes that COCCONI 1988 neglects the fact that the time delay due to dispersion by free electrons in the interstellar medium has the same photon energy dependence as that due to bending of a charged photon in the magnetic field. His limit is based on the assumption that the entire observed dispersion is due to photon charge. It is a factor of 200 less stringent than the COCCONI 1988 limit.

AABOUD 2017M analyze tri-boson W+- W+- W-+ production in decay channels with three charged leptons or two like-sign charged leptons with two jets, where the lepton can be an electron or muon. In the data, 24 tri-lepton events and 21 di-lepton plus jets events are selected, compared to a total event yield expected in the SM of 30.8+-3.0 and 21.9+-2.0, respectively. Analysing the tri-lepton transverse mass or the transverse momentum sum of the two leptons, two jets and the missing transverse energy, the following limits at 95% CL are derived for the form factor cut-off scale Lambda(FF)-->inf: -0.13 < f(S,0)/Lambda**4 < 0.18, -0.21 < f(S,1)/Lambda**4 < 0.27, in units of 10**4 TeV**-4, which are converted into the following limits: -0.49 < alpha_{{4}}() < 0.75 and -0.48 < alpha_{{5}} < 0.62.

To reduce systematic errors they determine the ratio of the branching fraction of this decay to that of Z --> mu+ mu- mu+ mu- within phase-space cuts imposed on lepton transverse momentum and pseudo rapidity, dilepton invariant mass, and J/psi transverse momentum. The number of selected Psi mu+ mu- (Psi e+ e-) candidate events is 29 (18). Analyzing the mu+ mu- and mu+ mu- lepton+ lepton- invariant mass distributions, a yield of 13.0+-3.9 (11.2+-3.4) events for the Psi mu+ mu- (Psi e+ e-) mode is obtained. The ratio of the branching fractions is determined as 0.67+-0.18+-0.05 within the selected phase-space cuts. Assuming extrapolation to full phase space cancels in the ratio, and using their measured value of B(Z --> mu+ mu- mu+ mu-) = 1.20+-0.08E-6, they estimate B(Z --> J/psi lepton+ lepton-) = 8E-7.

In the CM energy range 183 to 209 GeV HEISTER 2004A select 30 e+ e- --> nu nubar gamma gamma events with two acoplanar, high energy and high transverse momentum photons. The photon--photon acoplanarity is required to be > 5degree, E(gamma)/sqrt(s) > 0.025 (the more energetic photon having energy > 0.2 sqrt(s)), p(T(gamma))/E(beam) > 0.05 and |cos( theta(gamma) )| < 0.94. A likelihood fit to the photon energy and recoil missing mass yields the following one--parameter 95% CL limits: -0.012 < a_{{0}}^Z/Lambda**2 < 0.019 GeV**-2, -0.041 < a_{{c}}^Z/Lambda**2 < 0.044 GeV**-2, -0.060 < a_{{0}}^W/Lambda**2 < 0.055 GeV**-2, -0.099 < a_{{c}}^W/Lambda**2 < 0.093 GeV**-2.

ACHARD 2002G study e+ e- --> Z gamma gamma --> q qbar gamma gamma events using data at center-of-mass energies from 200 to 209 GeV. The photons are required to be isolated, each with energy >5 GeV and |cos(theta)|<0.97, and the di-jet invariant mass to be compatible with that of the Z boson (74 -- 111 GeV). Cuts on Z velocity (beta<0.73) and on the energy of the most energetic photon reduce the backgrounds due to non-resonant production of the q qbar gamma gamma state and due to ISR respectively, yielding a total of 40 candidate events of which 8.6 are expected to be due to background. The energy spectra of the least energetic photon are fitted for all ten center-of-mass energy values from 130 GeV to 209 GeV (as obtained adding to the present analysis 130 -- 202 GeV data of ACCIARRI 2001E, for a total of 137 events with an expected background of 34.1 events) to obtain the fitted values a(0)/Lambda**2= 0.00+0.02-0.01 GeV**-2 and a(c)/Lambda**2= 0.03+0.01-0.02 GeV**-2, where the other parameter is kept fixed to its Standard Model value (0). A simultaneous fit to both parameters yields the 95% CL limits -0.02 GeV**-2<a(0)/Lambda**2<0.03 GeV**-2 and -0.07 GeV**-2<a(c)/Lambda**2<0.05 GeV**-2.

AAD 2023BR use 139 fb**-1 at Ecm = 13 TeV. The off-shell Higgs boson production in the Z Z --> 4 lepton and Z Z --> 2 lepton 2 nu decay channels and the on-shell production in the Z Z^* --> 4 lepton (lepton = e, mu, AAD 2020AQ) decay channels are used to measure the total width. The off-shell Higgs signal strength is measured to be 1.1+0.7-0.6 assuming the same on-shell and off-shell coupling modifiers are used individually for gluon-fusion and for gauge-boson modes. The scenario of no off-shell contribution is excluded at 3.3 sigma. Combining with the on-shell signal strength measurement, the total width normalized to its SM expectation Gamma(H)/Gamma(H)**SM is measured to be 1.1+0.7-0.5 assuming the same on-shell and off-shell coupling modifiers are used individually for gluon-fusion and for gauge-boson modes. The observed upper limit on the total width is 10.1 MeV at 95% CL. See their Fig. 7. See corrected width values in their erratum AAD 2025AP.

The off-shell Higgs boson  production in the Z Z --> 4 lepton and Z Z --> 2 lepton 2 nu decay channels and the  on-shell production in the Z Z^* --> 4 lepton (lepton = e, mu) decay channels are used to measure the total width. The off-shell Higgs signal strength is measured to be 0.62+0.68-0.45 without the constraint on the ratio of the off-shell signal strengths for gluon-fusion and gauge-boson modes. The scenario of no off-shell contribution is excluded at 3.6 sigma. The results are shown in their Table 1 with other constraint scenarios and the decay widths assuming the same coupling modifiers for on- and off-shell couplings (g_{{p}} and g_{{d}} in their notation). The measurement of anomalous H V V couplings is shown in their Extended Data Table 1 and Fig. 8.

These results are then combined with the published results of the H H --> gamma gamma b bbar and H H --> b bbar b bbar, which use data of up to 20.3 fb**-1 at Ecm = 8 TeV. The upper limits on the g g --> H H production cross section are measured to be 1.6 pb, 11.4 pb, 2.2 pb and 0.62 pb from b bbar tau tau, gamma gamma W W, gamma gamma b bbar and b bbar b bbar, respectively.
