The LOw-Frequency ARray (LOFAR) has recently conducted a survey (LOFAR Tied-Array All-sky Survey;LOTAAS) for pulsars in the Northern hemisphere that resulted in discoveries of 73 new pulsars.For the purpose of studying the properties of these pulsars,we search for their γ-ray counterparts using the all-sky survey data obtained with the Large Area Telescope (LAT) onboard the Fermi Gamma-Ray Space Telescope (Fermi).We analyze the LAT data for 70 LOTAAS pulsars (excluding two millisecond pulsars and one with the longest known spin period of 23.5 s).We find one candidate counterpart to PSR J1017+30,which should be searched for the γ-ray pulsation signal once its timing solution is available.For other LOTAAS pulsars,we derive their 0.3-500 GeV flux upper limits.In order to compare the LOTAAS pulsars with the known γ-ray pulsars,we also derive the 0.3-500 GeV γ-ray fluxes for 112 of the latter contained in the Fermi LAT fourth source catalog.Based on the properties of the γ-ray pulsars,we derive upper limits on the spin-down luminosities of the LOTAAS pulsars.The upper limits are not very constraining but help suggest that most of the LOTAAS pulsars probably have ＜ 1033 erg s-1 spin-down luminosities and are not expected to be detectable with Fermi LAT.
