The detection of a coincident bright X-ray burst represents the first observed multiwavelength counterpart of an FRB. However, the search for similar emission at optical wavelengths has been hampered by the high inferred extinction on the line of sight. Here, we present results from the first search for second-timescale emission from the source at near-infrared (NIR) wavelengths using the Palomar Gattini-IR observing system in the J band, enabled by a novel detector readout mode that allows short exposure times of ?0.84 s with 99.9% observing efficiency. With a total observing time of ?12 hr (?47,728 images) during its 2020 outburst, we place median 3Ҡlimits on the second-timescale NIR fluence of ?18 Jy ms (13.1 AB mag). The corresponding extinction-corrected limit is ?125 Jy ms for an estimated extinction of AJ = 2.0 mag. Our observations were sensitive enough to easily detect an NIR counterpart of FRB 200428 if the NIR emission falls on the same power law as observed across its radio to X-ray spectrum. We report nondetection limits from epochs of four simultaneous X-ray bursts detected by the Insight-HXMT and NuSTAR telescopes during our observations. These limits provide the most stringent constraints to date on fluence of flares at 1014 Hz, and constrain the fluence ratio of the NIR emission to coincident X-ray bursts to RNIR ? 0.025 (fluence index ?0.35).   Search for WW gamma and WZ gamma production and constraints on anomalous quartic gauge couplings in pp collisions at root s=8 TeV 期刊论文  OAI收割 PHYSICAL REVIEW D, 2014, 卷号: 90, 期号: 3 作者:  CMS Collaboration 收藏  |  浏览/下载：91/0  |  提交时间：2015/12/02 CROSS-SECTION  LIMITS  LEP   Measurement of the t(t)over-bar production cross section in the dilepton channel in pp collisions at root s=8 TeV 期刊论文  OAI收割 JOURNAL OF HIGH ENERGY PHYSICS, 2014, 期号: 2 作者:  CMS Collaboration 收藏  |  浏览/下载：12/0  |  提交时间：2015/12/02 PROTON-PROTON COLLISIONS  GAUGE COUPLINGS  ATLAS DETECTOR  LIMITS   Measurements of W gamma and Z gamma production in pp collisions at root s=7 TeV with the ATLAS detector at the LHC 期刊论文  OAI收割 PHYSICAL REVIEW D, 2013, 卷号: 87, 期号: 11 作者:  ATLAS collaboration 收藏  |  浏览/下载：6/0  |  提交时间：2015/12/02 GAUGE BOSON COUPLINGS  CROSS-SECTION  P(P)OVER-BAR COLLISIONS  PARTON DISTRIBUTIONS  SYMMETRY-BREAKING  SEARCH  TEVATRON  PARTICLE  SECTOR  LIMITS   Study of exclusive two-photon production of W+W- in pp collisions at root s=7 TeV and constraints on anomalous quartic gauge couplings 期刊论文  OAI收割 JOURNAL OF HIGH ENERGY PHYSICS, 2013, 期号: 7 作者:   收藏  |  浏览/下载：19/0  |  提交时间：2015/12/02 GAMMA CROSS-SECTION  BOSON COUPLINGS  HIGH-ENERGIES  SEARCH  LIMITS  LHC  LEP   Measurement of the sum of WW and WZ production with W plus dijet events in pp collisions at root s=7 TeV 期刊论文  OAI收割 EUROPEAN PHYSICAL JOURNAL C, 2013, 卷号: 73, 期号: 2 作者:  CMS Collaboration 收藏  |  浏览/下载：11/0  |  提交时间：2015/12/02 GAUGE-BOSON COUPLINGS  SEARCH  LIMITS  LEP   Search for contact interactions using the inclusive jet p(T) spectrum in pp collisions at root s=7 TeV 期刊论文  OAI收割 PHYSICAL REVIEW D, 2013, 卷号: 87, 期号: 5 作者:  CMS Collaboration 收藏  |  浏览/下载：10/0  |  提交时间：2015/12/02 COMPOSITENESS SCALES  REFERENCE PRIORS  CROSS-SECTION  QUARK  LIMITS   Measurement of W(+/-)Z production in proton-proton collisions at root s=7 TeV with the ATLAS detector 期刊论文  OAI收割 EUROPEAN PHYSICAL JOURNAL C, 2012, 卷号: 72, 期号: 10 作者:  ATLAS collaboration 收藏  |  浏览/下载：12/0  |  提交时间：2015/12/02 TRIPLE GAUGE COUPLINGS  CROSS-SECTION  LIMITS  DECAY  LHC   Measurement of the t(t)over-bar production cross section in the dilepton channel in pp collisions at root s=7 TeV 期刊论文  OAI收割 JOURNAL OF HIGH ENERGY PHYSICS, 2012, 期号: 11 作者:  CMS Collaboration 收藏  |  浏览/下载：7/0  |  提交时间：2015/12/02 PROTON-PROTON COLLISIONS  QUARK PAIR PRODUCTION  TOP-QUARK  ATLAS DETECTOR  GAUGE COUPLINGS  LIMITS  BOSON  LHC   Measurement of W gamma and Z gamma production in pp collisions at root s=7 TeV 期刊论文  OAI收割 PHYSICS LETTERS B, 2011, 卷号: 701, 期号: 5, 页码: 535-555 作者:  CMS Collaboration 收藏  |  浏览/下载：9/0  |  提交时间：2015/12/02 GAUGE-BOSON COUPLINGS  HADRON COLLIDERS  AMPLITUDES  ZEROS  E(+)E(-)  SECTOR  LIMITS  LEP
