“…Aside from any UV motivations for their existence, LQs near the weak scale have been well studied in the literature [59][60][61][62][63][64][65][66][67][68][69][70][71][72][73][74], and have been frequently appealed to in order to explain various low energy anomalies e.g. in B meson decays [75][76][77][78][79][80][81][82][83][84][85][86][87][88][89][90][91][92]. LQs at the TeV scale manifest in a variety of scenarios.…”

A high energy muon collider can provide new and complementary discovery potential to the LHC or future hadron colliders. Leptoquarks are a motivated class of exotic new physics models, with distinct production channels at hadron and lepton machines. We study a vector leptoquark model at a muon collider with $$ \sqrt{s} $$ s = 3, 14 TeV within a set of both UV and phenomenologically motivated flavor scenarios. We compute which production mechanism has the greatest reach for various values of the leptoquark mass and the coupling between leptoquark and Standard Model fermions. We find that we can probe leptoquark masses up to an order of magnitude beyond $$ \sqrt{s} $$ s with perturbative couplings. Additionally, we can also probe regions of parameter space unavailable to flavor experiments. In particular, all of the parameter space of interest to explain recent low-energy anomalies in B meson decays would be covered even by a $$ \sqrt{s} $$ s = 3 TeV collider.

“…Some of these models can explain observed discrepancy in muon g − 2 [18,19] and also accommodate the excess of 2.4σ in a Higgs decay branching fraction to µτ at 8 TeV with 19.7 fb −1 luminosity [20]. Because of their great importance in elucidating several issues of flavour physics , leptoquarks have been studied in literature in gory details during last few decades [7][8][9][10][11][12][42][43][44][45][46][47][48]. In parallel, numerous searches for leptoquarks have been performed in different colliders [49][50][51][54][55][56][57][58][59][60][61][62][63][64][65][66].…”

Leptoquarks are one of the possible candidates for explaining various anomalies in flavour physics. Nonetheless, their existence is yet to be confirmed from experimental side. In this paper we have shown how zeros of single photon tree-level amplitude can be used to extract information about leptoquarks in case of e-γ colliders. Small number of standard model backgrounds keep the signal clean in this kind of colliders. Unlike other colliders, the zeros of single photon amplitude here depend on √ s as well as the mass of leptoquark along with its electric charge. We perform a PYTHIA based simulation for reconstructing the leptoquark from its decay products of first generation and estimating the background with luminosity of 100 fb −1 . Our analysis is done for all the leptoquarks that can be seen at e-γ collider with three different masses (70 GeV, 650 GeV and 1 TeV) and three different centre of momentum energy (200 GeV, 2 TeV and 3 TeV).
